Restoring MacbookPro

Hey everyone, to start out I am new to the forums and I have a few questions. I am thinking about restoring my Mac. I don't really have any problems with it or anything I just feel like I have a bunch of clutter. I am very organized when it comes to my files, but I still feel like I have a bunch of unnecessary files. Also after I restore it, if I do, I am planning on installing Windows on my Mac. I have read up on it and it doesn't seem to hard. It seems like boot camp pretty much does all the work for you. I am still kind of hazy on how to do it though. So if you guys know have to install Windows on a Mac please tell me and any tips will also be appreciated. If any of you also know how to restore a Mac any help is appreciated. I am pretty sure you just insert the disc that came with the Mac and hold C while it boots up. But again I am kind of hazy on it. So if anybody has any tips or knows how to do it I would greatly appreciate and help.

Any help is appreciated!
