i would want both the wireless router in the red area to provide internet access via DHCP to public users, and in the blue area, i would also want internet access provided (it doesnt have to be DHCP at all).

essentially i want both routers to provide internet access using the same cable modem. if i can set it up with the equipment i already have, then i will try it.

not too familiar with the DMZ setup but will try. Also putting host files on all computers connecting in the red zone is not an option.
In that case you don't need a DMZ.

As long as your current router has enough ports for the physical cables, and the wireless access for the rest then you should be able to set it up without extra equipment.

You can set everything up as the same network and restrict file access to certain computers via software firewalls on the private PCs. You should be able to use the free version of Zone Alarm for this purpose if you don't already have a firewall.
Yes, the soft firewalls is something I considered, my main concern is that i have two UPnP devices on the private network with Media sharing which is why I want to isolate these machines from the public part of the network. I do not want people accessing my xbox360 or NAS appliance.

I will setup the network today with the diagram I presented. Thanks.
