You do have to be careful with all those curves. I have done a lot of the sanding on my two ES guitars with 3M maroon and gray sanding pads. I use them dry, but I rinse them when the get clogged, and then re-use them when they are dry.
I don't think the holes make any difference, but I would not use any sand paper wet that does not say "wet-dry" on the back.
As to the rest, my notes are basically a copy of the procedure I got from McCreed.
