There are many possible answers to your questions. A residential treatment program may be his best bet. Consult with a few local DUI and/or criminal defense attorneys and hire the best one for the job.
I highly recommend requesting the DMV hearing, for a number of reasons. One, if you don't request it and it turns out you have something to fight, it is difficult if not impossible to overturn the suspension. Two, even if the hearing can't be won, requesting it extends your temp license and allows you to plan for the suspension. Three, if you don't request it, you will not see the police reports until the court date, if at all. Hiring an attorney will make all of these issues much easier to...
I agree with the other attorney's answer. Additionally, assuming that she gets probation on the DUI, paying of the restitution would be a condition of the probation, at least in CA. If you haven't hired an attorney on the DUI charge, I highly recommend that you do so. Good luck.
There are a lot of issues here, not the least of which is the felony charges. Most attorneys offer a free consulation. I highly suggest using avvo to find couple and giving them a call to explain the situation in more detail. Some attorneys may offer a military discount, and some will offer affordable payment plans. Either way, she will need an attorney. Good luck.
