They do have student rush - $25 cash/traveler's checks only. Seats are all the way to the right and are partial view. You will miss Roger DeBris' entrance in SFH, the right door in Roger's apartment, the bathroom in Max's apartment, among other things. But you can't beat the price.
I imagine Roger would be in unless he's sick.
Only place to get autographs is the stage door which is the same hallway that you enter/exit the theatre. Roger should come out, but he takes a long time if he does, so be patient.
Hope this helps and have fun!
