Jolly Green Giant's ultralight blog covers many options you might look into, he's bigger than either of us and constantly trying new products from the cutting edge.
Luckily for you (and I), you're at the top range of what manufacturers actually make.
You shouldn't have trouble fitting into any long size sleeping bag: 6'6" is exactly what they're sized for. I have wide shoulders as well (46L jacket size) and have managed to fit in bags reputedly on the narrower side like the Mountain Hardwear Mtn Speed 32. I've also been very happy with my Stoic 15F bag and Jacks 'R' Better long sized Stealth quilt. For value, I recommend checking out GoLite's new bags. If you've got NBA dollars, check out zPacks sleeping bags because they're awesome (really, every damn thing zPacks makes is killer in my opinion).
For shoes, look to New Balance for traditional padded trail runners. Personally, I'm very fond of Merrell's Trail Glove zero-drop shoes. They've got just the right amount of sole for the trail while drying extremely quickly and weighing very very little. I wear a size 15 US and I'm on my third pair. I've put in 40+ mile days tromping through dozens of streams with them without blisters or bruising.
Tents are the only area you might have some trouble. I use a hexamid twin from zPacks and absolutely love it. I've found its length adequate, and they recently released a 'long' version. GoLite's Shangri-La 2 shelter is quite long, I use that for ground sleeping in winter. I've hear good things about the length of some TarpTents and LightHeart Gear shelters (The LHG Solong 6 is advertised for those over 6'8"). For traditional options: REI's "plus" versions of their tents are as long as anything out there. I had a Quarter Dome T2 Plus from them several years ago that I would use for base camping and I had a 6'10" friend fit comfortably.
For general insulated clothing I've had luck with climbing and alpine brands like Mountain Hardwear and Arc'teryx. Climbers tend to be lanky and require longer sleeves and legs so they don't hike up when they're fully extended. Sometimes the sleeves are a bit shorter than I'd like. Oh well, First-world tall-guy problems.
