I know nothing about glass bead.
Soda blasting does require light sanding to give the hull some tooth. It's not difficult, and would certainly remove any caustic material. Then again, before you paint you want to wipe the hull down with something anyway.
My boat was soda blasted a few years ago (i've posted the story a number of times, let me know if you want the link). The hull came out very nice and it was easy to prep it for paint. Another guy in the same yard had his boat sand blasted and the hull was a mess - lots and lots of gouges, pits, holes, etc. He spent a lot of time filling and sanding.
