How to "move" Gameboy Advance SP parts+ speaker help

[Horrible N00B]

I have a GBA SP, a backlit one, that I'll modding. The main things that I'll need help with:
-Move buttons to new places (A B Light L R Select Start D Pad)
-Move linking/charging ports + battery
-Move cartridge slot
-Add a speaker, two total, probably by buying another one and putting it with the original
What should I buy, and how do I do it?
Even partial answers are welcomed.

1- Remove X.
2- Solder wire where X used to be.
3- Place X in its new position.
4- Solder the other side of the wire to X.

So what kind of wire should I get? I want to be able to buy it either from radio shack, amazon, or ebay.
