ASA5520 Routing/Subnet Configuration Help

Question

Hi,
I'm not much of a networking guy and need some help getting my ASA5520 to play ball. The general gist is that I have 3 subnets (xxx.xxx.1.xxx,
xxx.xxx.2.xxx, and xxx.xxx.5.xxx), two of them (.1 and .2) are on ASA1 and can see each other fine. One (.5) is on ASA2 and can see .1 (ASA2's outside interface is assigned a .1.xxx IP) systems but not .2. I believe it's because ASA2 has no default route for the .2 subnet and I have no idea how I would go about getting that set up. So there's my question, how can I make the .5 subnet on ASA2 evident to systems on the .1 and .2 subnets and viice versa?
For clarification here's a rough diagram of what I currently have:
                                  <---->xxx.xxx.001.xxx subnet<---->[ASA2]<---->xxx.xxx.005.xxx subnet--
INTERNET<-->[ASA1]-{
                                  <---->xxx.xxx.002.xxx subnet<---->
And here's what I need:
                                  <---->xxx.xxx.001.xxx subnet<---->
INTERNET<-->[ASA1]-{                                                   }[ASA2]<---->xxx.xxx.005.xxx subnet--
                                  <---->xxx.xxx.002.xxx subnet<---->
I really appreciate any help you can give me.

I got the network setup, but did not get what you are trying to do. Do you have 2 WRT54Gs there? Are you trying to turn off DHCP server of second WRT54G? A detailed information would be appreciated.
