Howdy. I backpack in the same area and have a pretty similar gear list. A couple things I did to cut wait:
-Pack. Switch to a lighter pack than than the Jam2. I went MLD and got a Burn, but if you don't think you can fit everything in there, the Prophet might work better. You could save up to 10 oz. with the Burn and I think it is a more comfortable and superior pack to the Jam2.
-Shelter. Seriously consider a lighter shelter option, or splurge for a really fancy cuben complete protection shelter of some sort (Lightheart Solo, Hexamid, Duomid with bug netting, etc.). I thought I would never give up the tent-like protection but the freedom and skillset of using a 4 oz. tarp and 6 oz. bivy for 10 oz. of total bug and weather protection is so cool and light (I do use a Duomid for more difficult weather). If you can borrow someone's set up and play with it for a trip, you might realize the weight savings and flexibility of this duo might be worth it for you.
-Pad. I recently grabbed a Neoair small (9 oz.) and put my pack under the bottom of my legs. Surprisingly, it works. I get the full torso comfort of the Neoair while shedding quite a few ounces.
-Quilt. Quilts are cool, particularly in the summer. I have a Nunatak Arc Edge -- 11 oz. which keeps me warm down to 40 degrees and packs down to nothing. A JRB Stealth would work great too -- and you'd be supporting another VA-based business.
-Random Things. You could probably lose another pound by some austerity measures with your water bottle selection, fire starters, pillow, seat, etc. but if you enjoy all those things, all the better. I just considered getting a UL pillow after spending a few years sleeping on my shoes, clothes, nothing, etc. I might sleep better.
