For the cook kit, if you're wedded to esbit, then why not take the bottom of a soda can and cut it off? It offers a nice "dish" area for the esbit to burn in and weighs ~0.25 oz (more or less depending on where you cut the can). Best of all? It'll cost you less than a buck.
Along the same lines, what kind of cooking are you doing? If it's FBC methods (which I recommend for long days on the trail; it's just easier overall), go over to a 2-cup system (you can find various deals out there on aluminum that'll weigh in the 1 to 2 oz range; personally, I like Zelph's reduced-capacity two-cup Foster's pot; scroll down to see it).
Can't really improve on the spork weight, but Wal-Mart offers a blue nylon spork in a 4-pack for about $5.
If you do return your EMS Velocity, then it might be worth a look at the Jacks 'R' Better Sierra Sniveller; it can perform as both a quilt (rated to 30*, conservatively) and a puffy layer around camp. Might allow you to remove the fleece from your pack; might not. Weight is 24 oz. for the long size. If you return your bag, the quilt would come out to ~$80 plus shipping.
For your FAK, what are you carrying? It would seem rather heavy for a personal FAK. For me, I carry the following: one pair nitrile gloves (avoid latex, due to some folks' allergies), two pieces of sterile gauze, an ACE bandage, a small baggie of meds (4 per day Ibuprofen, 2 per day Immodium, 2 per day Benadryl), a small tube of superglue (doubles as repair kit item and emergency bleeding stopper), a small spray antibiotic (Neosporin), and some vaseline-slathered cotton balls (doubles as firestarter and blister prevention).
For the water bottles, have you considered Gatorade bottles? They're widemouth, easy to use those shock cord loops everyone loves on their shoulder straps (the indent about a third of the way down the bottle is useful for that), durable, light, and less than $5 a piece.
As to the pad, if you do decide to go with a quilt, I'd go with the Thermarest rather than the Klymit, but it'd be worth researching pads before deciding on the quilt. I use an hammock (and, therefore, an underquilt rather than a pad), so I'm not as familiar with them as I could be.
