check out gregg cook (get cyced) on i tunes. I pod group motiontraxx.com often carries his stuff, plus they have some nice interval stuff which can be adapted for hill climbing intervals, particularly their treadmill intervals series. I think cook actually has a couple of compitlation albums which you can buy as well- 9.99 or thereabouts. Also a lot of the podrunner. podcasts have intervals, and a lot more have steady state workouts and various paces so you can work out your own climb series by gering up and down on a pre determined rate.
