Hi and welcome to TSG.
When I got my first MS cert (many moons ago) I did not use any materials that were purchased to help me study. I used hands-on experience and the internet, which has a VAST amount of information and free study materials available. I personally think that purchasing expensive materials from some of those sites is a waste of money when the information is available for free with a little research online.
There are many forums on the Internet dedicated strictly to IT Certifications. The one that I used to help me at the time has since vanished from view, but if I were starting fresh today I would probably go here:
http://www.mcmcse.com/forums/
One word of caution: stay away from any site that advocates braindumps, because that is CHEATING and will not benefit your education in the long run.
Unfortunately, Tech Support Guy does not have a forum dedicated to IT Certifications. I've suggested it in the past but the mods do not feel it is necessary at this point (yet, they have numerous non-technical forums so go figure.) If you do a quick Google search, you can find many reputatable forums which dedicate time to helping those who are seeking certifications from all avenues of technology.
I assume you have hit Microsoft's website to research the MCP?
Best of luck to you.
