Hi Jeffrey! I can't really add much to what Rachel has already said, but welcome to Aikido. I go to a dojo about an hour and a half north of yours, and I know my teachers know yours. I have heard really good things about your dojo, so I'm sure you are in great hands!
As far as rolling, I couldn't do a forward roll at all until I had been training for about 4 or 5 months, I think.....then I got injured (not rolling, though, LOL) so now when I can go back to rolling, I'll be back at square one. So, take your time, it's not a race!
