These are all good suggestions. I'd spend most of my time in the Jasper and Lake Louise areas if I was doing your trip. Banff has it attractions, but is mostly a tourist trap. Early November anywhere in Western Canada is a bit of a crap shoot. It could be sunny, gorgeous and autumn-like, or it could be snowing and blowing. Either way, many photo opportunities.

Bookmark this page, as the forecasts are usually pretty accurate and you'll have some idea what to expect when you start your trip. Good luck!
