Need help setting up pre-owned MacBook with time machine backup

So my wife spilled a lot of hot cocoa on my MacBook last week and it gave me an excellent excuse to upgrade. Luckily I backed it up using time machine in October. So i found a unibody MacBook with a 250gb HD for a great deal on craigslist and snagged it up. I already loaded snow leopord onto it, but hereare my questions:
1.) how do I erase everything from the first owner to get it like a fresh MacBook?
2.) how do I restore all the stuff from my time machine backup to get it like my old MacBook was set up?

Thanks

 

Thanks. After searching for awhile I found the instructions on apple.com.
