My MSI ms7093 motherboard states that it takes DDR-SDRAM on their website (and eMachines says so to) up the 400MHz. What is it? (There is a story behind my question involving me being removed from BestBuy, my usual guy was closed)

I want 1 GB 400MHz
What is CAS latency? do i want the # higher or lower?
Also if anyone can suggest quality RAM for under $60 for the pair as i'm buying this off of Newegg or TigerDirect now.

Based on what you said: 400 MHZ =PC3200, CAS stands for Column Access Strobe http://hardwarehell.com/articles/ras_cas.htm Your emachine board will time to the Standard CAS 3.0 for PC3200 Here is MSI's page, This says you can use dual channel. In dual channel mode you should be using a matched pair of pc3200 dimms.
The name says it all -- 59 and holding permanently

That motherboard has four expansion slots with a capacity of 1GB in each slot with of either PC2700, PC3200, or PC4000.

The lower the CAS latency the better the performance.

As Oldf@rt has suggested you should use matched pairs when running in dual channel, you can use different manufacturers but the specs need to be exactly the same, but if you are going to be using you computer for applications like video editing or three D imaging you will be better off purchasing matched pairs from the same manufacturer.

Thanks guys. Im planning on buying either a "Dual Channel Pack"(2 sticks, same box) or 2 of the same part number(2 identical sticks in separate boxes).

Next (fairly simple) question is can I still use my current RAM (2x256) with the new 2x512 for a grand total of 1.5GB RAM

In order to use all four modules in dual channel they must have the same specs but can have different capacities.
