I'm sure you'll get lots of good advice, but I just want to say that I've learned I can do a lot more than I think I can when pushed to do it! I've done some serious hills between Carlsbad and La Jolla (San Diego). Specifically, Torry Pines. It's not easy, but what a feeling of accomplishment! And I did it having absolutely no idea what I was getting myself into!

As Floyd Landis said at a thing I went to recently, "The best way to get good at hills is to climb hills." I'd say just do the best you can to prepare and then go with it. Do the best you can.

You can do it!!!
