It really depends on your height. If your legs are longer, you should use that to your advantage and use the leverage of a longer crank. If you use a longer crank and don't have long legs, you can feel like you're riding a hear or two higher than you actually are, so make sure you don't get cranks that are too long!
Usually not. It'll be fast at the start, but a small crank will limit top speed unless you can turn the pedals really fast.
A 3-piece BMX crank set typically consists of three separate components: two crank arms and a spindle.

Yes you can, but take it to a bike shop or someone who knows what they are doing

Haros are the best and damondbacks with small cogs are the best BMX in the world.
