How to bridge two wireless routers for a single network?

I'm thinking of using two Wireless LAN router-switches from two different manufacturers in different rooms to create a single network for a multitude of devices. How is this done (see extended explanation)?

My current setup relies on a Buffalo WHR-G54S with the excellent open source DD-WRT firmware flashed as a replacement for the shoddy original. It's in the bedroom, connected to three machines with an ethernet cable. A fourth ethernet cable runs to the living room to the Xbox, and this is something I want to get rid of.
In addition to the Xbox, the living room houses a Nintendo Wii and the odd laptop, all of which connect to the wireless LAN. An unconnected PSTwo sits there as well.
Lately I've been eyeing Apple's new Airport Extreme with its gigabit ethernet ports. Since I've already got a wireless router, I thought maybe I could get rid of the annoying room-to-room cable with it. Here's the planned setup:
Airport Extreme is the main router in the bedroom. It connects with wires to the three machines there, and creates a 802.11N Draft 2.0 wireless network secured with WPA, let's call it MyWLAN.
In the living room is the Buffalo router. It bridges to MyWLAN and connects as an ethernet switch with standard 100Mbps wires to the Xbox and the PSTwo.
A couple of questions:
1) Is bridging two discrete routers in this manner possible? The Buffalo need not provide wireless connectivity to any clients (the signal from the bedroom AP reaches the wireless devices in the living room just fine), it just needs to be bridged to MyWLAN and to act as a simple ethernet switch for the wired connections, forwarding the DHCP IP addresses provided by Airport to the clients.
2) Is it possible for a single network to have both a 802.11G and an 802.11N router without the speed dropping to G level? (This seems unlikely, even if the G device is somehow configured to not actually provide any wireless connectivity to clients.) That is, can individual devices connect with different speeds; say, a recent Mac could connect with N, and older devices (including the bridged Buffalo) would connect with G?
All in all, this looks like a real bitch to configure, but assuming it's possible (and the DD-WRT firmware is quite capable), I'm willing to make the effort just to get rid of the damned bedroom-to-living room cable.
