I'd suggest sanding them with 80 grit first and then using finer grit, maybe 400-600, or until you like the finish.
Use an orbital sander or better yet, a large variable speed disc grinder.

Actually, I used an orbital sander on the hot tub on Sunday. I used 60 grit and the grit fell off the paper pretty quickly. It helped, but I went through 4 pieces of sand paper (1/4 sheets) and it still left quite a bit of the tool marks. They are quite deep.
Here is the after picture.
I have a belt sander and I'm seriously considering getting it out and buying a new belt. Is there any sandpaper designed for this kind of job?
Also look at this picture. Is this normal for flagstone to have this material flaking/spalling on top? Some of the stones are like this, and some are not.
