I think the best thing you can do to help enjoy your first rehearsal is to pester the conductor to let you have the music before the rehearsal.  I think going over something that you've already been over at your own pace is much easier than trying to sight read everything.
My wife and I have had two violas off Liz - we think they are fantastic too.
At the moment my needs are rather more basic than that.

I need to be able to bow on one sting at a time (not 2) and to get some feel for how to pitch the notes. My (always insecure) alto clef reading is now quite pathetic...
I have rediscovered the pain factor of sore fingers and an aching shoulder...

Rehearsal is on Thursday but I don't know anyone connected with the orchestra. If I can stuggle through the first night (Delius, Barber & Franck!) I can take the music to look at over the next two weeks (half term). The concert is in 4 weeks time

wow! what a challenge! especially if you turn up and find the viola section is quite small!
I play the viola in an easy pieces string orchestra which needed more violas, despite the fact that the violin is the only instrument I have ever really learnt on.
You mention a number of specific worries. In relation to getting a feel for pitching the notes I'm not sure if
this might help. It was written with violin in mind so you would have to substitute CGDA for GDAE.
As to reading alto clef, I am told this comes with practise although I wouldn't know since I don't get round to practising that much! In the meantime, for recognising the notes on the stave it might be worth making yourself some flashcards. It is also possible to make flashcards representing (for instance) the finger positions for the different notes of a C major 2 octave scale. Might even get round to doing that myself sometime.
As to reading different keys,
this is a bit of a short term swindle, but I'm still doing it this way. I know it's not really what you should do, but it's a trade off of how much time I'm prepared to spend doing viola scales (ie none) against a desire to play in various keys. It has enabled me to read simple viola music confidently in any key without learning any scales. Given that you only have 4 weeks to the concert, it may be of some help in the short term to at least be aware of the simple repeating pattern which underlies the positioning of the fingers in any major scale in any given position. On the other hand I am the only person I have yet found who understands what I am talking about on that point, so please don't waste too much time on it if it doesn't seem to make sense!
As to bowing on the wrong strings, it sounds like you just need to re-find your right arm elbow levels by bowing on some open strings when you warm up.
I like to think wrong notes get buried to a certain degree in an orchestra, but it would help if you aren't playing too loudly. AmandaL I think has mentioned not putting too much rosin on. You could always keep your mute on as well!
In terms of "crash course" preparation for a concert, I think it is really helpful to have recordings of the pieces you are going to play, and to read your part through whilst listening to the pieces. That way you will identify where you are exposed, and what the most difficult parts are. Often a section that looks quite black turns out to be quite straightforward, whereas a fairly simple looking load of crotchets in a presto or a scherzo can be quite a finger twister or another innocuous looking section can involve some quite difficult counting. But being a music teacher you probably know that side of things much better than I do anyway.
good luck on Thursday!
