Going to Jasper via Kamloops and hwy 5 is a good route. There are some provincial parks along the way. My favorite is Wells Gray, though that involves a side trip. The main access road is paved to the first campground (and the major waterfalls). There is also a PP closer to 5 near the town of Clearwater.

Close to Jasper is Mt Robson PP. At least stop at the vistor center and try to get a view of the mountain.

Go to the Canadian Nat Parks website to get lots of info on Jasper and Banff. The 'newspaper' they give you at the gate is available online as pdf. It lists all the campgrounds, as well as sights and hikes.

Hwy 16 is a through route from Alberta to BC. 93 Icefields Parkway connects Jasper to Banff. Hwy 1 is the through route from Calgary to BC (including the Canadian Glacier NP). 93 exits Banff into Kootenay NP (and Radium Hot Springs).

93 continues as US93 to the west side of (US) Glacier.

To go down the east side, I'd suggest taking hwy 40 from Canmore through several Alberta parks that rival the national parks for views. Pickup AB22 at Longview and go south to AB3. 3 crosses into BC and runs all the way to Hope. Or you can jog the other direction and head south to Waterton and US Glacier.

Going to the Sun has length restrictions. If you can't drive it, US2 is a fine way around the south side of the park.
