What do I specify as my gateway on my access point?

I'm attempting to setup a NoCat node in Eugene Oregon, but I have a few 
questions that I couldn't find answers to in the documentation. My 
setup is as follows:

wireless clients
   |
   |
access point
   |
   |
eth1
linux box with nocat gateway (10.0.1.2)
eth2
   |
   |
switch (internal wired network)
   |
   |
router box (hardware, not linux) (10.0.1.1)
   |
   |
The Internet

I want some wireless clients (members of the owner class) to be able to 
access my wired home network and others to only be able to access my 
outside Internet connection. Since I want the members of the owner 
class to effectively be on my internal wired network, I don't want the 
linux box running nocat gateway to be doing any NAT routing (I want to 
be able to run a server on a wireless client and access it from my 
wired network). Let's ignore security issues for now.

So:
1) Should my wireless clients, access point, and eth1 be on a different 
subnet then my wired network?
2) What do I specify as my gateway inside my access point setup (I'm 
using a LinkSys WAP11)--the linux box (10.0.1.2) or my gateway to the 
Internet (10.0.1.1)?
Thanks!
