Patrick, did you get a chance to take a look at my gear list, and the thread that accompanied it? It's not a perfect list by any means, but it should give you an idea of what you can get away with and how light you can actually go.
You should be able to shave a lot of weight off your total just by making a couple of key changes.
Like Serge said, ditch the tent and get a tarp. That should be your first move, as it'll lighten your load considerably. That's a fine tent for solo backpacking, but for fastpacking and running, you should really go lighter. You did say you're cool with roughing it, after all. ;) Honestly, I wouldn't even call using a tarp roughing it. I sleep way more comfortably with all that ventilation, and I get a killer view.
Depending on what you have to spend, you can save more than 2.5 lbs. Even if you don't have much money at all to throw at it, you can save a lot of weight by just using a blue tarp from Walmart or wherever and some lightweight cord for guylines. My setup cost me around $60. I bought an Integral Designs Siltarp off gear swap for $40, a good deal of Air Core line (also off gear swap) for $10, and six Easton stakes for ~$10. Total weight for that whole setup? 9.15 oz, or about 1/6th of your tent's weight!
Get a lighter pack. You should be able to find something that'll suit your purposes perfectly and weigh a fair bit less on gear swap. If you keep your eyes open, I doubt you'll spend more than $80.
Lots of savings to be had with hydration as well. Use a 1 liter plastic soda, water, or Gatorade bottle for < 1.5 oz. Use a 1 liter Platypus bottle (1 oz) as backup in case there's an area where you have to carry more water. It's collapsible, so it's easy to pack. Total weight savings? Nearly a pound!
Driducks don't really weigh a pound, do they? I generally just carry a windshirt, anyway. I don't care if I get wet when I'm moving fast, as that'll keep me plenty warm, even in low temperatures. When I stop, I'll just put the tarp up and get under my quilt.
Do you really think you'll need the gloves for your summer kit? That shaves 5 oz.
Again, if you know the Whites like the back of your hand, you shouldn't need the SPOT. Take off another 5 oz. I envy your knowledge of the Whites, by the way. I need to spend more time up there…
You can DEFINITELY cut down on your first aid / survival kit. Does that even include things like sunblock, bug spray, Bodyglide, and identification?
My quart-sized ziploc bag that contains all of my miscellaneous items weighs 7 oz, and I plan to shave 2.5 oz off that total by repackaging my sunblock and bug spray. This ziploc contains my first aid materials (ibuprofin, medical tape, tweezers, a few bandaids/gauze bandages), chapstick, cottonballs (firestarters), firesteel, superglue, identification and cash, a bic lighter, and Bodyglide.
I keep a small knife with a few micropur tabs in another ziploc in my pack's side pocket.
What else do you really need for first aid and survival? No need to pack winter items, because this is for summer trips.
Between all of the above, I think you can shave 4 lbs off your list. That's going to feel awesome on your back!
Now, some things I think you forgot to add:
-Are you carrying a pack cover or liner? I'd recommend it. I use a 2.5 oz trash compactor bag.
-Like you said, you need a sleeping pad. Figure 3.5-5 oz.
-Are you bringing a camera? I guess your cell phone could double, but I like having an actual camera on my trips. When fastpacking, I take very few pictures, but often do a video journal while moving.
-Are a knife (or razor blade) and compass included in your survival kit? Even if you know the Whites well, it's worth having a compass and perhaps a low detail map in the event that you get turned around and find yourself off the trail.
Those items will probably add half a pound or so, but you'll still be in far better shape if you can take advantage of some of that weight savings. You should be able to do everything for under $200.
