For reference, my kit is heavier than yours and I also carry redundancy in fire-starting, medical supplies and water treatment. I have had to use all three in different situations.
I see a couple of places you can shave a little, for a little:
--Compass. You've got a nice one, but check out the 24-gram Brunton Trooper. There's a thread on it in Gear Deals and I can vouch for it as an effective tool for map and XC use (also becomes your e-mirror).
--Knife/Multitool. That Mora you mention above is a cool idea, but so is a carbon or stainless-bladed Opinel #8. Large blade, under two ounces. Leathermans are beefy/heavy for what you get. I love'em, just not in my backpack.
--Folding Bucket. Okay, I carry one of these when I'm in groups, and also what you can replace it with: 2-gallon ziploc. That's large enough to fill, suds, shake and rinse with for laundry. Ounces saved.
--Tent Footprint. Personally, I don't want to buy a new tent or have a leaker, so I use one...just not the BA version. Some 2-mil painters plastic is beefy enough to last on your trip, but lighter by maybe an ounce.
To me, you have a solid kit with reliable products.
