phat bahsturd: Since you're not completely sure what you want to upgrade too I would recommend you keep riding your current bike. After several months you'll know what you like and don't like about it and will have time to come up with a list of features you'll want in a new bike.
I'm not familar with the Bianchi you mentioned - what would you gain by upgrading to it over your current bike? Say for example the only real difference is going from 10 speed to 14 speed. Is the upgrade cost worth the 4 extra gears?
