Based on your current hill climbing experience, I suggest calculating the lowest gear you would like to have, along with desired high gear. That will then give a starting point for suggestions. For instance, my low gear is a 39 x 25, and high is 53 x 12. There are a variety of ways to get the same gears, but that works for me because I prefer a tight-ish ratio for the type of riding I do.
