I would save your $100. Your receiver will allow you to use a optical digital audio cable (TOSLINK) from your PS3 to get 5.1 surround sound. The only thing you are not getting with this setup are the new HD audio soundtracks. Unless your watching Blurays all day long your not missing a ton. Even if you do watch blurays all day long, you will need an HDMI audio receiver which will be around $300 minimum. And for that $300 all you are gaining is ease of use and the DolbyTrueHD and whatever else the PS3 may support in the future. You don't need HDMI 1.3 because the only practical thing you gain is the ability to bitstream HD audio, and the PS3 cannot do that anyway. HDMI 1.1 or 1.2 is all you really need, although 1.3 will give you piece of mind. Read some of the "why you don't need 1.3 threads". An HDMI receiver is convenient in that you don't have to switch multiple devices to do something.
As for a switch... Unless your TV only has 1 HDMI input and you have 2 or more HDMI devices, I would save my money until I could afford a receiver I liked.
