To answer your original question which I failed to do in the previous post, I wouldn't consider this "too nice" for a first road bike. It seems just right. I would not bother upgrading parts as they seem to be about right, but of course it is worthwhile to do a tuneup with new cables, housing, bar tape, etc.

The best upgrades for a bike like this are a nice saddle and clipless pedals. Both of which can be transferred to another bike later on. My favorite saddle has probably been on 5 bikes I've owned.
