My current setup at home includes a Linksys cable modem, plugged into the Linksys VPN/firewall/router, plugged into (among other things) my Linksys WAP+router.

I chose Linksys... well, just because, I have no affiliations, etc etc.
Personally, I'd go with just the wireless AP (no router). The AP+router is nice to have because you can then consolidate your hardware into one machine (don't need the router). Also, you can plug the AP+router into your existing router... but then you could just buy the access pointer without the router built-in.
I like having the individual pieces, because if one goes down, it's cheaper to replace than an integrated peripheral.
