Wow, talk about a run-on sentence and lack of punctuation!
Anyways, you'll need the OS disc(s) that came with your MBP. Put the disc in, restart and hold the "C" key. Follow the install instructions.

Or a full retail install version of Leopard or Snow Leopard. Pop the disc in, boot and hold down 'C" after the chimes, go to Utilities and selecrt Disk Utility and partion the drive in GUID mode and format, back to the installer and select your language, let it run and then update from the Apple web site.

How much room is in the stall? Could be a one-person at a time deal, meaning you're on your own.

What source is the OSX you're trying to install coming from? Describe it by version, and appearance.
