you're getting a nice drivetrain, so why change it out? If you're short on funds just do the upgrades you need now for commuting & touring (racks, bags, etc), and ride the bike for awhile to see how you like the brifter set-up.
If you really want to do it just change the brifters to bar-end shifters and standard brake levers. Shifters will be about $100 new (don't know if they work of ten-speed cassettes), and levers about $40. Look on ebay for cheaper stuff. The FSA Vero crank is a square taper BB which is sealed, so it'll work nicely for the rough,wet, and dirty roads you'll find ahead of you on commutes and tours; maybe just swap the 30t ring for a smaller 26t.
