In my blog I have described a route through the Rockies I took earlier this year as part of a 2 month excursion to North America. The Rockies tour was a round trip from Vancouver and by hired car and hotel: I know your proposed trip is a little different, but my experience may give you some ideas.
One part I will do differently on another visit will be the direction of travel on the Icefields Parkway. The dramatic effect of the scenery is, in my opinion, a function of the distance from Banff. It's all pretty amazing, but I would suggest South (Banff) to North (Jasper) will keep your jaw dropping all the way. (It's a bit like the canyons of the SW USA: best to see the smaller ones first and end with the Grand Canyon for maximum effect).
Anyway, wherever you go in the area you will be impressed. Have a great time.
