italian isn't really odd sized, just one of the major systems in use in recent history. The threads on the fork will be Italian as well, 25.4mm instead of 1". That's not a lot of difference and in fact an English headset can be used, although the fit will be kind of grade-b. The other things you need to worry about are rear OLD spacing at the dropouts and seatpost size, and whether the frame was designed for recessed (allen) brakes or nutted brakes. Aelle is okay, not as sprightly as the more expensive grades of tubing. I'd think about $100 is tops for this grade of frame and fork, but I know that depends on where you live as much as anything...
