Definatelly normal for the first few rides, and you bum will probably hurt from the saddle a couple of weeks too. Unfortunate about the fall, I would blame that on not being completely used with the new bike and it's control rather than balance and all. Brakes take a little time to bed in properly and you can easily panic and squeze them too harsy. This happened to me when I picked up a brand new bike and almost ran a red light
The other's advice is excellent, practice slowly in a safe area and get familiar with the bike.
