How often does the federal reserve meet and also, does anybody have a website that shows prime, MTA, Libor and all the others info currently and previous data?

You can try Mortgage-x.com for current and past index data. It has some lead generator tabs that you should stay away from but has very good statistical info on there as well.

As far as the fed see

http://www.federalreserve.gov/FOMC/

The Federal Open Market Committee "FOMC" holds eight regularly scheduled meetings during the year, and other meetings as needed.

bloomberg.com is another good site to use. It shows the market, rates, bonds, and trends.
