I'd get either a compact crank or a cassette with larger cogs, or both. As I said, I can climb just about anything with my setup. However, regardless of gearing, you still have to climb more to get better at it. Until you change the gear, just climb whatever, and wherever you can, as often as possible. Know that it gets better with more time doing it.

Or, rather, as Lemond said, "it doesn't get easier, you only go faster". So true...
