I have installed some new Cas latency 2 spec memory. In my bios I have the Cas Latency set properly. How do I know if I have the Ras-Cas set properly, and the Precharge set properly. I now have all set to "2". And what exactly do these mean

Those are the latency ratings. "2" is faster than "3". As for the correct settings, what brand is your RAM? Are the latency ratings written on the RAM?
