The ripjaws should work just fine for you. There is a shell shocker deal coming today at newegg for 2x4GB 1333MHz ripjaws X so you should probably check that out.
I assume you are on a really tight budget to make the selections you are making. Could you actually list your budget so we can tell a little better what we are working with here?
Maybe there are other suggestions for better components we can make.
As for PSU: quality one from Antec, Corsair, Silverstone, Seasonic or XFX.
Don't skimp out on the PSU, it's the one component in your machine that if it fails it can take every other component with it.XFX 450W
