I decided not to try covering it in anything - more sheetrock, thin plywood, some kind of veneer - because above all, I didn't want it to take up any more space than necessary. The post itself is a 6" x 8" beast. The problem, as with most of the things I've been redoing in the garage, is that whoever installed it was an asshole. The post isn't centered in either the top or bottom bracket, and the top bracket isn't centered on the beam that it's supporting. Plus, it's slightly rotated. And the whole length of the post is a bit warped. All of this explains why the former sheetrock job was so terrible, but now it's my problem.
As usual, I went with "simple." I bought some wood putty and did a few rounds of hole and crack filling. I cut a few knotty corners out and added a few clean pieces of wood in their place. I ran a plain, rounded router bit down the length of the post to get rid of sharp corners that I was sure to walk into in the future. I sanded the hell out of the whole thing a few times. And I decided not to try to do anything with the top bracket - easier just to cover it up with some kind of moulding. I put all of my scrap lumber and rudimentary trigonometry skills to use and came up with something I'm pretty pleased with.
