It's a freaking amazing show. I've had the privilege of directing this as well as acting in it (I decided to make Debra a straight male instead of a lesbian female, but my actor dropped out a few weeks before the show, so I stepped in for the role, much to my disappointment), and I wish you much luck.
Your theatre is most likely going to have an old lady playing Kimberly (which I highly disagree with. I had a teen in old lady makeup), which means that you, Jeff, will most likely have to makeout with someone very much older than you...just letting you know. It's a fantastic role. I wish you the best!
