Need advice on 802.11n strategy (running two wireless routers)

Ultimately my question is this: Using my two routers, can I create two
wireless access points and keep one of the access points pure
802.11n?

Here are some details: I have both an Airport Extreme and a D-Link
DIR-625 router.

My plan is to have a wireless N (the airport extreme) and a wireless A/
G (d-link) access point on my network. The goal is to preserve 802.11n
speeds, but allow other wireless devices to exist also. I already have
the routers working together, however I noticed the speeds on the 'n'
dropped when a device connected to the non-n access point.

I have DHCP disabled on the D-Link, and I connected the ports lan-to-
lan. I made a few other modifications to prevent IP collisions, etc. I
can successfully connect to either of the access points with any of
the devices below.

Macbook Pro (n)
Macbook (n)
iPhone (non-n)
Wii (non-n)
Also, an external HD plugged into the Airport Extreme

I believe it was the Wii connecting to the (D-Link, non-n) network
that slowed things down. While the Wii is on, accessing the external
HD via the Airport Extreme slows down the file transfers to non-n
speeds.

So, given this hardware, can I create the environment I'm looking for?
Also, is this common for people who care about network speeds?

Thanks!

Both routers have only fast ethernet.
