There are only a small number of schools which offer distance learning, so it shouldn't be a problem for you to contact all of the schools before you make your choice.
The main thing you should look for initially is the quality of their notes, since this will be your main source of information. I would be careful about any school which won't send you a sample of their notes, or invite you in to look at their notes. In your case, that will obviously include any computer-based material.
The next most important thing will be the brush-up course - narrow it down to a couple of schools, then see if you can sit in on a half hour or so of a brush-up course to see the teaching style and talk to the students.
You should also look for a school which responds quickly to your queries. You will, no doubt, need help from instructors as you study, and knowing that the school will respond to your e-mails quickly is a big boost.
There are lots of past threads about which is the best school, and you will see a couple of names coming up over and over again (and I'll add my name to the list of people recommending Bristol, who have supplied all of their notes, and lots of additional material, on CD ROM for longer than anyone else as far as I know). But this is a very personal thing - pick a school whose style suits you, which doesn't necessarilly mean it will be the same school that suits other posters.
Good luck!
