A friend of mine has an auger / post hole digger for his 35hp tractor. Can I run it on my 60 Hp tractor or will that damage the auger since I'm assuming they're rated for different HPs?

Worst that can happen is you break a shear pin, or get it stuck in the ground. Bring a big pipe wrench with a long extension in case you need to reverse it out.
BobG is absolutely right. Keep your machine throttled down and go slow into the hole. I always start the hole with a hand post hole digger to keep the auger from wandering and to keep the holes reasonably in a straight line. After a few holes youll figure out what you should and shouldnt do.
I'm not a fan of running my auger at idle. There isn't as much power in the hydraulics to lift it out and clean the hole. I'm at 1,200 to 1,500 when I drill my holes, and sometimes I will step on the gas pedal to get even more RPMS for additional hydraulic power when needed.
Here's what I use to clean out my holes after I auger them. It doesn't seem to matter what RPM I run, the auger never completely clears the hole of all the loose stuff. I gave up on those crappy clamshell diggers years ago.
