Bmx bike building

[Matt]

Right as my car is going off road again for abit
I'm going to have to bike it, I can borrow one for now, but going to rebuild my bmx as it's f*cked lol

So bike people, what do I need?

I have a full bike, two bent wheels, rusty bars, f*cked brakes and the chain/bearings are f*cked I think

Can any bike people right a full list of all parts to build a bike, kinda like a check list, so when I take mine to bits I can see what's usable and what's not.
Plus I have no idea what I'm doing, anyone wanna right up how to take apart the crank (I think it's a crank, and would I benefit from a different one? No idea what's on there now, what's best)
Plus any other upgrades



Much appreciated
