Oh, specialty tools you'll nee for assembling the bike would be the BB tool depending on what sort of BB it has. A thin 15mm will be needed for the pedals in most cases. And if you're going to service the wheel hubs you'll need cone wrenches assuming cup and cone bearings. And if you're going to get into truing and tuning the spokes then a set of spoke wrenches. GOOD spoke wrenches. That isn't the place to skimp. Other than that I can't think of anything specific unless it's a threaded headset. If that's the case you'll need the big flat wrenches in the right sizes so suit. Typically 32 and 28mm's. But check first as there are lots of other oddballs. The rest of the tools you can fake with a bit of care.

A headset press is one such animal. Many a person fakes it using a length of 1/2 or 5/8 all thread rod, washers and nuts. Use wraps of masking, electrical or duct tape to center the rod in the middle of the head tube and the nuts and washers to press the cups into place firmly. If you have to install the lower race onto the fork you can often find a short section of pipe with a clean end and use that as a slide hammer to tap it into place. If you do this keep the blows light and make sure the pipe keeps moving side to side so it walks the race down evenly and with as little stress as possible.
