A bit of advice I put on here frequently - as do others. Don't try to cram too much distance and places into a trip!
We love Glacier and you have two sides of it to cover. The east side is laid back and more for hiking - and perhaps biking. The west side is the commercial side but also at least one nice but not overly difficult hike - Avalanche Lake.
Going To The Sun Road is amazing and should be done from both sides to Logan Pass - and some hiking up there as well. Leave early in the morning to drive up. Cycling has some restrictions on it.
Leave the Coast for another trip - trust me on that one.
Not sure what you are looking for in campgrounds. We stay at the KOA on the east side and North American on the west side.
PM me if you would like - have been there a few times.
