Hi Don, sorry about the shoulder. Know how you feel; I've had problems since high school with my left rotater cuff, though not nearly as severe as your injury. Lighter packs were a necessity for me because of shoulder pain. Anyway, on with gear.
First, IMO you should be very cautious about your pack selection considering your injury. I think a pack with a real frame is necessary; the frame will much more effectively transfer weight to your hips and support the load without placing too much weight on your shoulders and upper back. From your choices, I would choose the ULA over the GoLite just for the frame, and I would add the optional stay. You might also consider the Osprey Exos series that was just released, or the Granite Gear Vapor Trail. Or if you have the money and want to buy your last pack ever, you could get a McHale ;)
As for the bag, I would choose the Versalite over the Ponderosa, though both are too warm for summer. If you can sew, make yourself a light synthetic quilt for summer; it shouldn't weigh more than a pound or so. With this and the Versalite, you're ready for anything short of serious deep winter cold.
For the tent, I would choose the Scarp over the Hubba, but for summer the Scarp might be a bit warm in the Southeast. You can set the Scarp fly up without the inner; I would get a light bug shelter of some sort to use in hot weather. This would also allow the option of bug-free sleeping either out under the stars or in a tail shelter. It should also be much lighter than the inner tent, saving you weight in the summer.
With these changes, you could be around 5 lb. warm- weather/ 7 lb. cold weather weight for your "big three". That's a huge savings! Good luck with the rehab!
PS: Thinking about it, I really would seriously consider the McHale. Your probably talking $500-600 and 8-10 week wait, but really that's nothing if you love the trails and it allows you to hike pain-free.
