OK

I also don't see in this situation where you would need multiple IP

It is because I want the wireless devices (behind the WRT) to be able to
talk to the PCs, but *only* the PCs in the showroom and not the rest of the
LAN, the 520, or the internet.

That led to the original suggestion of having them in a separate mini LAN,
using a second NIC with no bridging between the dual NICs.  Given that
configuration, it is easy for me to see how it would work the way I want.

If I fed the WRT WAN port to the regular LAN switches and don't have them
using a different IP address, how do I route the wireless devices to the
desired PCs without them also seeing the other PCs and 520 etc?

For that matter, once the WRT is in a different IP range and subnet, won't
it need a default gateway or route to the LAN to find the desired PCs even
if they are in a different subnet?  And once I do that, why can't they see
everything else too?

I have a feeling I'm missing something really fundamental in what you are
suggesting.  :(
