You may want to check out Inside Banff : First time visitors here at TripAdvisor.   Although that page focuses on Banff, the points that it makes are applicable — with minor variations — to the entire Canadian Rockies region.

Note that any visit to Banff National Park (or any other Canadian national park) requires the purchase of a park pass.

If you are struggling to decide whether to stay in Canmore, Banff townsite or Lake Louise, you may be able to get some help from the Tripadvisor page entitled Inside Banff National Park : Banff vs Lake Louise vs Jasper.
