I have a couple questions about snowboard bindings?

It sounds like in bindings you would be a medium. I personally don't like the Flow bindings because I find they don't provide as much support as I like, but my dad has them and he loves them 'cause he doesn't have to sit down and strap in, and plus it's faster. If you would like the easy strap in bindings I'd say go with Flow because they specialize in that type so they are proven to be good. I ride the Burton Men's Freestyle with capstraps because they are comfortable, sturdy, and a decent price of $180 Cdn.
