Where is a bottom bracket on a bmx bike?
Installing a mid bottom bracket is very simple. All you do is tap both bearings into both side of the frame evenly, they do not have threads or anything like that its just simple pressure, don't hit it to hard though because you could crush the bearings.

The bottom bracket where 3 frame arms meet is supplied with ball or roller bearings which are able to reduce friction very substantially.

Can a 19mm bb be changed to a 22mm bb?
Unfortunately not, or at least not in any reasonable manner... It's one thing to get a spacer made for the tube welded to the frame which would allow you to use a smaller-than-stock bottom bracket but to go larger you'd literally have to cut the bottom bracket housing off of your current frame, grind the connecting pipes to a larger radius and then weld a larger bottom bracket housing in place of the original small diameter housing. Keep in mind that if you decide to try this, the frame MUST be made of steel. Carbon fiber or Aluminum will be a disaster. However, as I mentioned earlier this will NOT be a fun ordeal and unless you have extensive welding (and cutting) experience it won't go well.
Would a three piece crank for a mountain bike work for a BMX?
yes... if you have the right bottom bracket... it has to fit the cranks as in 19 20 21 or 22mm most likely......... and it has to be the right size for the frame.. if its bmx it will probably be US size or euro, spanish or standard. if you find the right bottom bracket with the right size bearings then yes..
