Skateboarding...?

I want to start skateboarding, and would really appreciate being told everything you know(: I'm not really worried about how to do anything etc. right now, I'm more focused on quality of things, like which brands are better etc. Should I pay more for good bearings, or does it matter? I'm guessing... show more I want to start skateboarding, and would really appreciate being told everything you know(:

I'm guessing high, medium and low trucks means how far it is from the ground to the deck, but which would be best?
