I have the 06 Bianchi Volpe and have put about 3000 touring miles on it so far. I made minimal changes: saddle, pedals, and tires. Then added touring specific things like racks, fenders, etc etc.

FYI, I am 6'2 and ordered the 58 Volpe and there is no issue with heel clearence (with 36ML MEC panniers).

Get the bike and ride it around for a few months and gradually change what you want until you are comfortable.
