A general rule of thumb is to keep your gateway at the 1 address. The second router, the wireless one I believe, should be something like 192.168.1.2 (again to keep things simple). Then you can make the print server 192.168.1.3. If you just randomly assign stuff, you're just going to have a cluster of a network and it'll be a pain in the ass to work with if you need to down the road.
