+1 to the lifetime tuneups. Index shifting can be a real pain in the unmentionables, and having someone to tweak it when there are problems is a big plus. Later on, you get more familiar with how to deal with that stuff, but for now it would have some benefit.
Plus, a good LBS will offer you fitting before and after the bike is bought. One LBS around here will do fit sessions for the life of the bike, in addition to the tune-ups.
