You shouldn`t use two of them, just go for a security suite. I`m using norton internet security suite and i haven`t had any problems.

Except for the firewall, a nice anti-virus software is also necessary.

Use anti spyware softwares. Google also provides anti spyware software , you can download that too from Google software pack.

If you are using a good Internet security like Norton or Google spy-ware doctor than you don't have to worry about your computer security.

Don't install too many firewalls, because later on they corrupts or hangs your PC at any moment.
