If you are moving to outboard bearings and saw lots of paint or other reason maybe but unless your heading out on a tour a shortened bearing life might not be a big deal and could then have it done.
Facing and chasing a BB are two different things. As far as facing being required, what is required is to figure out if the faces are square and parallel, there are a few ways to do that, and most times they are GTG on most frames.
