How do I reset a Mac?

[Ricochet J]

I have been given a 2011 Macbook Pro by my gf. I'm moving over from Windows. I'm quite new to Mac OSX. I think it has Lion or Tiger on it. The software updater says I can have a free upgrade to Mavericks.

My questions:
1. How do I reformat the HD, and install Mavericks?
2. Before my gf gave me the laptop she bought MS Office from the App Store. If I start from fresh, with my own Apple ID, how do I install MS Office?
3. I need a partition for Windows 7 or 8. I was told to use BootCamp. What's the best way to do this?

Thanks!

You won't be able to install Mavericks on a Macbook that old. Mountain lion or Lion wouldn't work either. I think the latest you can install is Snow Leopard.

To install Mavericks, you need one of these Macs:

iMac (Mid-2007 or later)
MacBook (13-inch Aluminum, Late 2008), (13-inch, Early 2009 or later)
MacBook Pro (13-inch, Mid-2009 or later),
MacBook Pro (15-inch or 17-inch, Mid/Late 2007 or later)
MacBook Air (Late 2008 or later)
Mac mini (Early 2009 or later)
Mac Pro (Early 2008 or later)
Xserve (Early 2009)
Your Mac also needs:

I'm sorry for the typo! The Macbook Pro I have isn't 2001, it's 2011!!! I've updated the OP.

At the moment it has Mountain Lion on it.
