Home Network Setup

I'm looking for advice on some new networking gear for home. I have the following requirements:

• gigabit
• wireless (would like 5ghz rather than 2.4ghz to prevent interference with bluetooth, etc.)
• router (DMZ required would be great if I could have 2 devices in the DMZ)
• 8 wired ports (again gigabit)

I've got a NAS that I like to stream to multiple devices in the home. I currently have a WRT160N that is starting to act up and needs to be replaced and connected to that I have a 5-port Linksys 10/100 switch.

I don't mind purchasing multiple components (e.g. router + A/P + switch) if that's the best way to go. Just looking for some advice on the setup and gear that you all may recommend for a setup like this.

Thanks in advance...
