1 piece cranks need the 1/2 inch pedals while 2-3 piece cranks use 9/16th.
Just to help the newbies out there. OPC or one piece cranks mean the arm that holds the pedal is just one piece of steel that goes from pedal to pedal through the bottom bracket (where the bearings ride). Those only use ½" size threads on the pedals.
3 piece cranks are identifiable as each arm is separate and bolted onto the spindle which is part of the bottom bracket. 3 piece refers to 2 arms + the bottom bracket. Only 9/16" (which are bigger than the ½") threads fit those arms.
Don't forget the left arm is backwards thread, so to loosen you turn it righty tighty. The right arm is normal so lefty loosy to remove.
Snafu. They make medal pedals that are very light weight and have changeble spikes
A crank (or a crankset) is the thing that sits in the middle of the bicycle, has the chain on it and have the pedals attached to it.

BB usually stands for Bottom Bracket, the part which holds the cranks/pedals to the bike
It is not recommended, your feet can slip off the pedals and you can get hurt.
The only thing on a BMX regularly called a spindle would be the crank axle. Although I suppose one could use spindle for the pedals and the wheel axles as well.
The main parts are: frame fork wheels (handle)bars saddle seat post cranks pedals
It depends on your hub. If it's unsealed, then the ball bearings have different diameters - you just need to find out which size you need. That's fairly easy. If it's sealed, there is going to be a number on the side of the seal - usually a 4 digit number starting with a 6. That number identifies your bearing dimensions, that's the bearing size you need.
Assuming that you are referring to a bicycle, this is what you will need: -frame -handle bars -headset (the bearings and bearing races that let your forks turn inside of the head tube) -forks -seat and seat post -crankset (the inside workings of the crankarms and pedals), crankarms, and pedals -sprocket, hubgear, and chain -brakes and brake cable -rims, tires, and inner tubes and grease
Different BMXes have different axle sizes. Easiest is to measure what you've got.
Bmx's don't come in sizes. They are all one size.
The only thing I can think of that would make a sound on a regular BMX would be the ticking from the pawls in the freewheel/freehub mechanism - the one way clutch that allows you to keep the pedals still while rolling forward.
