Your kit sounds good to me I'd like to try out the 10-20mm one day. I find my most used lens for landscapes is the DA 16-45, I also have a 55-300 for more reach and wildlife. Sometimes it's hard not to go wide in the Rockies, so make sure you mix it up!
You may want to check out the ebook series,
How to photograph the Canadian Rockies by Darwin Wiggett. These don't talk a lot about equipment but rather is a photographic to iconic and lesser known locations. Each location includes gps data and are all very accessible without a lot of hiking (if any). I purchased the series last year, and I think it's a great guide for travelling photographers to the Rockies.
If you had an iPad, Check out the Stuck on Earth app. I love this app for checking out images and getting a feel for the location. If you don't have an iPad, then you could try google earth - same idea.
Enjoy your trip, if you have any question feel free to ask, this is my backyard
