You're pretty much on target. Base weight includes the pack and everything in it except for "consumables" such as food, water, and fuel. This isn't a contest so don't worry that those in other areas may not include bear canisters.
ADDED on EDIT:
My baseweight used to be 30 to 35 or more pounds- all made of supposedly lightweight gear. On a weeklong trip I would generally start at about 50. Last summer I got the base down to about 17, and under 30 for a week. This summer I want to knock a few more pounds off and add a tent. For last year's hike I replaced my pack, rain parka, rain pants, and cooking system to save 10 pounds. Beyond that the weight saving was by reducing my kit list. Thanks to REI's recent sale I have cut 2 more pounds with a new bag and pad.
The pack is tricky. You can get a somewhat lighter pack to carry a 25 pound base. That wouldn't be the same pack you would want for a 15 pound base though. From my research it seemed that the ULA Catalyst and Six Moon Designs Starlight were good for a 15 to 20 pound base including the bulky bear can. (I have the Starlight) These packs are bigger than needed for 10 pound base weight and no bear can.
ADDED on another EDIT:
Since I'm a recent convert I'll go into some details. I always used to laugh at the "gram weenies" but the grams do add up to ounces and the ounces add up to pounds.
Cooking. Eliminate any redundancy. I cut my kit from about 3 pounds to 20 ounces and the UL folks think I'm way heavy.
Clothing. Your list looks heavy. Save weight by eliminating spare items. Choose non-stink fabrics and wash them mid-day then put them back on to hike dry. For the Sierra with a warm sleeping bag I was fine with shorts & polo shirt for hiking, wind pants & light fleece pullover for lounging, Marmot Pre-cip & ULA rain kilt for rain, one spare change of socks and underwear. My carried clothing and raingear was under 40 ounces.
Stuff. I cut, and cut, and cut at the little items. First aid kit had been over a pound. Lights, repair stuff, etc. was over a pound. For blister care/prevention I have switched to Leukotape, which is also my bandaids and gear repair tape. The packaging, zippered first aid kit, multiple stuff sacks and ziplocs added up too. Eventually I cut the 3+ pound pile of misc. items down to under a pound. At least this exercise didn't cost much money.
A great benefit of cutting weight from your pack is then you get to cut down on your footwear because it doesn't have to support all that extra weight. I never wanted camp shoes because my shoes are comfortable.
