wireless networking for gaming

I have 2 pc's an xbox 360, and a nintendo wii all connected via a d-link wired router. Recently I purchased a linksys wrt150n wireless n router because I want to move the to consoles to another room without running cables and because I want to use my nintendo ds (which is wireless only) online. My intention is to keep the two desktop computers wired and all the game systems wireless. Here is my problem. The DS only supports wep which from my understanding in very poor security... and I would much rather use wpa which works with everything else in my network. My idea is to use both routers together with the pc's behind the wired d-link router... and connected to that would be the wireless linksys router with my game systems either using wep or just open. Is this possible or even practical to keep my pc's safe behind one layer and the other with just the game systems basicly open?

 

Get a cross-over cable and look at this link -
