Yes, it's fine. Sand away!

The riser marks are the big bumps on the face. The little goosebumps you're talking about are just texture, a form of finish that hides surface irregularities. The riser marks are actually formed where the plastic is injected into the mold. Both can be finish-sanded smooth. Just be careful and don't go so far that the throat opens up. Only take off enough to remove the texture and make 'em smooth.
