If you use the pile driver the top of the pipe it will get bunged up but you can just cut that part off with a hack saw. The pipe actually cuts fairly easily. You can also make it easier on you by taking your time.
The brackets I use do not require any drilling. You just tighten the nut when the deck is at the right height. I did find out it's imperative to use four bolts that attach to the pier instead of taking a short cut and only using two diagonally.If you only use two, like I have been doing, the pier can sag down a little.
