I had to take the driver's side cam gear off. I just broke the bolt loose when the old timing belt was still on and torqued it after I put the new belt on. I was holding on the crank pulley with my homemade tool. It went ok with that, didn't seem to put too much stress on anything. Although, having the right tool is certainly the better way to go.
I think you could also make a nice custom strap wrench using an old timing belt, that should hold a lot stronger than a smooth strap wrench.
Otherwise, yeah, doing the timing belt is not that bad. I think the only thing I found on the second car I did it was that putting the oil pump back on while the water pump was still off was a bit easier, a little more room to work.
