The f22 belt seemed pretty straight forward to me(certainly not as complicated as an h22). The back balance shaft isn't terribly complicated, just honda's way of making sure that everything is aligned.

The sequence of looseing and tightening the tensioner was a nothing special, but just like anything else, kinda tricky the first time.

As far as the crank bolt goes, my 600ft/lbs impact wouldn't even touch it. I ended up having a friend hold the crankshaft tool on the end of 3ft breaker bar and I used a 4ft piece of pipe on the end of another breaker bar attached to a socket on the crank bolt. After about three or four tries it finally broke loose. Since then I purchased Ingersol Rand's 1000ft/lbs impact and it worked fine on a motor I was building for a friend, I didn't even need the crank pulley holder to get the bolt off, only to put it back on and torque it.
