Now then, some of you mentioned that if she's good, go for it. I haven't met her, just had a brief e-mail exchange, and I have no idea how good she is, or isn't. Supposing I start lessons with her, how will I know if she's good or not? I've never had music lessons before. And, I'm not even sure if she's ever played viola herself!
You should try to have a few lessons with her on a trial basis just to see if you get along with her OK.
Find out what her qualifications are (I would suggest she should have a minimum of grade 8 violin or viola to teach a beginner).
You could ask her to play for you (either violin or viola). If she doesn't sound good then she may not be able to help you to produce a pleasant sound (although this may be due to other reasons).
What is the highest level that she teaches ? (she might only teach to grade 5 or 6 and then pass pupils on to someone else).
Do her pupils obtain good marks in exams?
How quickly does she expect her pupils to progress?
You might also want to find out about her teaching methods -does she just concentrate on exam repertoire or will she work on other pieces with you?
Does she seem interested in her pupils?
Is she used to teaching adults?
Does she actually like the viola? (some violinists are very negative about violas and you wouldn't want to put up with that sort of attitude from a teacher for long).
Can she read the alto clef?
You could find out what she actually knows about viola repertoire - she should know enough about it to be able to select appropriate pieces for you to play.
How experienced is she as a teacher? Good teachers who have been teaching for a while usually have waiting lists.
There are loads of other questions you could ask.

I certainly agree that I will need a more specialise teacher later on, but what sort of level are we talking about before switching? G3? G5?
You should be OK with a good violin teacher up to at least grade 5. After that it depends on the way that they play.

Got my other 4 viola CDs through whilst I was on holiday.

Which CDs did you get?
