Re: Do I need a firewall being behind a router? I'm going to say no, you don't.
The firewalls built into Routers are pretty solid. I find the software firewalls built into Windows pose more problems than they offer in "protection". As long as you've got the absolute minimum ports opened in your router (if any), you should be fine.
Firewalls don't stop viruses.
If someone does manage to breach your router firewall, your PC-based firewall will be a piece of cake.
Spend your time shoring up your router firewall, for 95% of people, it's completely sufficient. Secure your router password, choose a very secure WPA2 passcode, and turn off any kind of automatic UPnP on it.

+1 Aye to that lad!
UPnP usually isn't a big issue, depending on the area you live in and what trouble makers you have. But no, not a huge concern for most people.
As with all things security, educate yourself you are the first and last line of defence on your own system.
