Question on behalf of bloke on Betfair

Here's what he asks, I told them you guys would know:
-------------------------------------------------------
"o.k. Here is my current setup

Wireless Router 1 connected to internet via a cable modem in the 'uplink'
socket.
Connecting Wirelessly to this router are 2 laptops.

Now I also have two other devices
Wireless Router 2 )and Wireless Bridge.

Can I do this:

Connect Wireless Bridge to the uplink of the second wireless router and have
2 other devices connected to the second wireless router, 1 via ethernet, 1
via wireless.

My theory is that the Wireless bridge will connect to the second wireless
router and then share that connection with the other devices.
I would effectively have 2 networks (two SSIDs/two encriptions keys of
course).

but the first router would only see one connection (the bridge) and that
connection would be shared (via NAT) by the 2nd router with the other two
devices.

The main reason is to share the internet connection, a bonus would be to be
able to share the printer connection, an extra bonus would be to be able to
share files.

(I may have to port forward and decide that only 1 device on the 2nd network
can connect to the printer)"
