Sorry about the late response. In terms of advice for your M1 year at Rush, keep in mind the fact that the administration have been instituting pretty significant changes in the curriculum since I was a first year. That said, here goes...
If your undergrad experience was anything like mine, med school is going to quite a new experience for you. Be prepared for wrote memorization of random minutiae like you've seen before, because that's about 80% of your first two years of med school. One of the great things about Rush is that on the first day of every quarter, your professors will give you syllabuses, which are essentially binders containing comprehensive notes for that course.
Don't waste too much money on books!!! In most of your classes, the syllabus will be more than sufficient to ace the exams. A lot of M1s (myself included) will panic at some point and end up buying textbooks that we never end up using.
I would try to attend all of you classes for at least the 2 weeks or so, and then decided which you can afford to skip. Since most of the syllabuses contain everything you need for the exam, there will be some classes where you'll gain little from attending...when I was a 1st year, those courses were biochem and physio. Anatomy, on the other hand, had lousy notes and you definitely had to go (esp. to gross lab).
I'll try to think of more stuff...and I'd be more than happy to any other questions you might have.
And yes, we are as friendly as we seem on the tours
