Seems to me that finish has no grain. So as long as you sand things to a fine enough grit for the buffer to remove you should be able to sand any which way you like...
Yup, what the fool said
You really do have to ensure you get all previous sanding scratches out as you move up the grits. The other thing I would suggest is to not worry about wet sanding. I've done the dry sand thing and honestly, after wet sanding the last guitar, I actually like it better and it only takes a wipe of a paper towel and about 10 seconds before you see your progress. My bet is you'll go through less paper by wet sanding and It seems like you get a better rub out by wet sanding too. You can use mineral spirits with the EM6000.
Also, I'd go up to 1500P minimum and 2000P to be on the safe side (this last rub out shouldn't take long at all) before you go to the buffer. I learned alot on the last guitar I finished (just a couple weeks back) and I've changed the way I do things which I think are for the better for me.
