Drive train question: Shimano vs. Sram I have both in 9 speed versions (Sram red 11-34 and Shimano xtr 11-32). Both are great. I'm replacing most cassettes with Sram & sram chains because they are easier to change (chain) and the price is a little better. Nine speeds are a little sturdier because of the extra width. However, if a great discount is available on Shimano, no problem.
Imho, there is no substative benefit going bigger than a 34 in your situation because that would produce a negative ratio. That means you would have to spin more than 1 revolution to turn wheels around once. Anyway, try any one and see for yourself. At some point you'll have to replace it (as they wear out) and you can always change it the next time to match your own experience. Don't worry-be happy!
