Help with my setup please

Hi everyone,
I wanted to ask the brilliant people on tom's hardware a question about my home networking setup  

Currently I have my cable modem -----> Belkin router (with wireless turned off) -----> linksys gigabit switch (feeding LAN to 8 rooms around the house) -----> 2 Linksys Wrt54g used as APs (one upstairs, one downstairs)

Now, the Belkin's IP is 192.168.2.1. I tried to set the WRT54g to 192.168.2.3 and it would give some kind of renew ip lease warning and lock me out from getting back into settings (tried 192.168.1.1 and .2.3) unless I reset it and started over. So, I left them as 192.168.1.1 and 192.168.1.2 and Im getting internet just fine on both of them. When I tried to go back to the linksys menu wirelessly and wired and add security, I couldn't get to it with the linksys ip's. However, it did allow me to go into the belkin's settings using 192.168.2.1 when connected to either linksys AP.

So my question is, is there a problem leaving the IPs on the linksys APs as they currently are or is that not a "proper network" between devices connected to one AP and the other? I read somewhere that it should be 192.168.2.253 and .254, but i dont want to mess with them again if I dont have to. Any help would be appreciated, I want my home network to be perfect.
