I've only been to Tallinn a couple of times on day trips from Helsinki, so I can't speak directly to the question of independent travel in the Baltics, but I have read a bit about the problems of travel in the area. It seems they are lacking in interconnecting railways, so that's out, although I understand there is bus service.

The Estonians seem to have mastered the use of at least tourist English, but I'm not sure about the other states.
