I must say, Chris, that you seem to have it together so well already that it is difficult to believe that you are a realtively novice backpacker. Surely you must have been lurking here for a while, right? But we absolutely love bloviating helping newbies, here, especially ones as excited as you obviously are!
Yes, you can cut ounces from almost anything on your spreadsheet, but the question is “Is it worth the money?” And most of it probably is not, at this stage. (We tend to discuss dollars per ounce as a metric, here, believe it or not.) You’re correct- your best payoff is going to be those items you highlighted in yellow. And, yes, buy a new pack last. Are you looking for specific product recommendations, or just generalities? If you want specifics it’ll help to tell us what you have rather than just the generic descriptions in your spreadsheet.
I’m one of the people who think that tent footprints are a scam, so you could lose half a pound right there just by leaving it behind. Unless you tend to camp in some pretty extreme conditions a tent is going to fail in some other catastrophic way (or more likely you’ll replace it when it gets ratty) long before you shred the floor severely. What you’ll get is pinholes, and those can be fixed just by smearing a dab of SilNet on them when you get home. Well, that’s assuming that the floor is silnylon; you’ll need a different product for urethane. But don’t get a urethane-coated tent, they are much heavier than silnylon.
FYI- there is a website called lighterpack.com that is a spreadsheet for tracking your hiking gear, and will break it down in various ways for you. It’s easy enough to do this on your own spreadsheet, though. But just so that you know the lingo, we often speak about “Base Pack Weight” (BPW) here. That’s the weight of everything you carry except consumables such as food and water, and that’s what we judge pack weights by because the food and water is variable. BPW what we fanatics try to get below 10 pounds.
You’re young, and youth seems to be a strong indicator for who can sleep well on just a closed-cell foam pad such as a RidgeRest or Z-Lite without needing more padding. (BTW are you a back sleeper, a side sleeper, or a belly sleeper? It actually makes a difference for sleep system recommendations…) Anyway, you could try one of these out and see if they work for you- they’re pretty cheap, and they are certainly durable, and many are light.
If you need just a little more comfort you can do what I switched to as I aged: I used a full length (72-inch) but incredibly thin (1/8-inch) Thinlight evazote pad from Gossamer gear, but also a torso-length (S or XS) Thermarest Prolite self-inflatable pad. This works because legs tend not to need a lot of insulation or padding- only your torso does- and your head will have a pillow (or something serving as a pillow). This is still reasonably light, and the 1/8-inch evazote is enough insulation for your legs and also provide some extra puncture-protection for the inflatable, as well as being large enough (but still light because it is so thin) to obviate the need for a ground sheet in a floorless shelter. Both of these pads are comparatively inexpensive, and you can often find the Thermarest on sale.
You could use some other torso-length pad, of course, but those get expensive fast as they get lighter. The ProLite seems to be in a sweet spot, IMHO. A thicker closed-cell foam pad as a torso pad would work too, of course, and be even cheaper if you can sleep on them.
Later on I switched to a Thermarest NeoAir for an even better weight/comfort ratio, but those are expensive.
58oz for a solo shelter is indeed quite a bit out of the range that we fanatics here would consider acceptable for three-season use, but that’s a big purchase. One much lighter option that can be done relatively inexpensively is to try a silnylon tarp, but it can take some practice to learn to pitch one well, and some people just can’t stand tarps. Heck, a lot of people can’t wrap their brains around any sort of floorless shelter, which is a shame since I’ve long been a lover of pyramid tarps. See here as well, if you want even more fanboyism. I use a bivy to keep out insects and other wildlife, and I much prefer it to an inner net- it also replaces a groundsheet.
The recommendations for a hammock are worth considering, especially if you like the idea of finding remote spots away from other people, which you seem to. I don’t understand why more people on the east coast don’t use them- there are trees everywhere back east, so no shortage of spots to pitch them. (Here in the west where you’re more likely to want to sleep above treeline it can be harder.) You can also pitch in places that no one would EVER consider putting a tent, like on slopes or over creeks. The whole subject of hammocks would need it’s own discussion, though. And you wouldn’t need a sleeping pad, but you should get some sort of under-quilt. Hammocks can be cold because they offer no insulation between your bottom and the cold wind, leading to a condition known as icy-butt. Using a sleeping bag doesn’t help, because laying on your insulation crushes it such that it doesn’t work. Some people just lay a pad in the hammock, but that is usually cumbersome, and the experienced hammock users all seem to prefer under-quilts.
But as I said, that is all a conversation of its own- if you’re interested let us know. There is also a forum called (aptly enough) hammockforums.net. A feature-rich and truly light hammock can be expensive, though, when you include the under-quilt, bug netting, and tarp. Jumping in can be quite a commitment. Good brands include Warbonnet, Butt-In-A-Sling, and Dutchware.
Your “camp sandals” seem heavy. A cheapo pair of rubber flip-flops is adequate, if you don’t want to wear your shoes all the time. That’s what I do.
What is your stove? How big is your cooking pot? What kind of food are you preparing?
There is an entire forum here at BPL for buying/selling used gear, and it can be a great place to get some deals. if you are risk-averse, stick with sellers who have several pages of posts here. Or, there is also an entire forum about making your own gear, which can be incredibly inexpensive.
