If you have the summer for your trip - don't hurry and don't plan on certain miles or speed per day. I think we checked out every area through B.C., Yukon and Alaska and we had plenty of time for the whole trip. We didn't make reservations except for 2 places which I mentioned in your other post. They were for July 4 weekend in Palmer, Alaska and 5 nights in Denali's Teklanika campground and those were only made about 3 weeks prior when we could better judge when we'd arrive.
I'd recommend not to overplan your trip. You'll have a better time and less stress.
