Help Im A Noob

first let me say my names tyler and im 14. i have a trek 4300 w/ disk and my friend and i go biking at a park by us that has tons of great trails.

could anyone assist me in a good site to buy a new set of peddles? possibly ones for shoes that clip in, because we bike alot, and as we get older, we try more and more crazy stunts, and last week i went off about a 10 foot jump strait onto some large gravel pieces and i slipped off my pedals and fell of and got banged up pretty bad. but thats half the fun
also i just got a helmet cam, so when it stops pouring uncontrolabley i hope to go out and try it out!
also does anyone know a good way to paint bikes? im a great airbrusher and really good with spray paint, but i dont see a good way to keep the paint from scratching off? possibly like 50 coats of clear coat? lol
welp i g2g eat thanks for looking
