Yes- you've got a good start here but it won't really tell you everything until it has everything.
What I do is pick a certain trip (maybe one that's typical for my area) and build a list that includes all of the clothes I would take, my 2.25 pounds of food per day, small items, stuff sacks, etc. That's when the real refinements will emerge.
For instance, I used to carry too much fleece and redundant clothing. I probably saved more weight there than you would in a tent. It's what helps prioritize your gear changes and updates. If your list has a warm down jacket and you're planing for a summer trip, it's pretty easy to trade for a quilt and sleep in the jacket for dual-use.
Adding everything such as your empty fuel canisters will bring up some interesting weight areas too. A canister stove is light until you consider the weight of the canisters. This is where an alcohol stove really beats it.
After those cheaper items, you can look at the big 3- pack, shelter, bag. A 16 oz pack and a 16 oz bag used with a puffy insulation jacket would drop 53 ounces (3.5 pounds) which is a lot.
Have fun with this and beware- it can get really insane! That said, trips are so fun with a lighter pack. You have a solid starting point. Doug
