there's some books out there that go over the more popular touring routes at the pass. I'm sure you will be able to find one in Golden and Revelstoke when you get into the area. Check Valhalla, they probably got some.
What kind of vehicle do you drive? If you are really poor - you should just sleep in that. The cabins in the park are by reservation only, and they fill up fast - and you need to pay for a membership for the Alpine Club of Canada on top of the cost of renting the cabins.
They get A LOT of snow up there, much much more than Kicking Horse and Revelstoke, so don't ski the slackcountry of those hills and judge the snow/avalanche conditions at the pass off of the stuff around the ski hills.

The pass is big, mostly alpine, and the approaches are long. Don't say you weren't warned.
