Congrats, you must be lovin it! The Shimano 105 and other components are nice upgrades for the price diff between the 7.5 and 7.6. I wouldv't got a 7.6, but none of the shops around here had my ideal frame in stock (20"), and Trek is out of them. so would've had to wait for the 2008, or go out of the midwest to locate a 2007. I almost got the 17.5" 7.6FX that was in a shop here, but forum members here recommended I test ride a 20", and it turned out to be a better fit. One thing I like better about the 7.5 over the 7.6 (besides the color ) is the slightly wider tires (7.6 has 28, 7.5 has 32), since I have a rack on it and am loading the bike up with some weight for commuting.
