Yeap, it looks like 2 HDMI and 2 component.

That switch will work fine. Here is 1 that also has Digital Optical outs (fiber) if you use that for SS. Does your Cable box have DVI or HDMI? If so, you can use that for 1 HDMI input, PS3 for the 2nd HDMI input, 360 for component 1 and Wii for component 2... Since you can use the PS#/360 for your DVD player, that should do.
