I'm in Vancouver and have done Baker and Adams in the past few years and am doing one more this summer although I haven't decided which yet.
I actually find I am most comfortable hiking in my vibrams, even with a 45 lb pack. The lack of weight on my feet makes climbing a lot easier, and they dry out in no time. I had a great time with them on Adams up until we hit deep snow at which point I switched to my plastic boots mainly out of fear the vibrams wouldn't cut it. I actually had more trouble with the boots than I did with the vibrams. After camping, I did the summit in plastic boots and crampons of course, but there were plenty of people who went up in these weird studded trail runner type things.
One thing I like to do: wear dress socks underneath wool socks. It cuts down on chafing, feels nice, and is warm.
Dehydrated mashed potatoes = awesomeness if you have a stove and water
I typically just carry water and dry food with me and skip the stove if it's just one night, but that's just me.
It's better to overpack a little bit and have some stuff left over when you get back to the car than it is to underpack and run out of water.
Do some easy stuff first. The summers here are dry and warm and you can easily survive outside at night with nothing if you get stuck/lost. If you do that at high altitudes, in the winter, or when it's wet, you're kinda screwed.
