Unless you're creating separate subnets for some reason, you don't want any routing or metrics in the wireless stuff. You do want to make sure that you have it all in bridge mode, if selectable, so they basically act as hubs/switches.
Sorry, I don't know more about the specific netgear devices although I have used the ADSL routers (wired only) and think they're great products.
Try ringing netgear support, when you have a free day to stay on hold. they're usually pretty good and can at least direct you to support pages.
