While it doesn't make as large of a difference as clock speed, latencies do indeed affect overall system performance and should be kept in mind when buying memory modules. However, if your memory modules can run at latencies under CAS 9, you should be mostly in the clear. Once you get under CAS-8, the performance gained is fairly small.
