It would be easier to evaluate your list if it were better organized. For examples, click on "Community Gear Lists" under "COMMUNITY @ BPL" on the right hand menu.
Is it 31# for both? 15.5# each isn't too bad, although for the conditions you outline, could be much lighter. To significantly cut weight, there are plenty of lighter options for tent, sleeping bags, and packs.
You could drop a couple pounds refining FAK, dropping filter for Aqua Mira drops, losing redundant (and heavy) water bottle, different stove, etc. Again, study some community gear lists for examples.
If it were me, and I already owned the gear on the list, I'd prob. go with it for this trip, then evaluate and lighten up accordingly for future trips.
