Computer security

My OS is win 7 Prof 64 bit and this is a follow up to John's response in ID 40518098.
How do I implement the following advise :
"
 put your machines behind a good commercial router with built-in hardware firewall for added protection. I do this as well.
"
My PC has Verizon DSl and the account comes with a telephone service.  This Verizon modem from where the Ethernet cable is connected to the PC is how the internet is accessed.  I doubt Verizon has a firewall of its own on its modem, but maybe the Experts can advise.

While reading a blog on this subject, it was suggested :
           " A two-way firewall monitors inbound and outbound traffic to-and-from your computer."
Hope u could please give me a link to a 'good commercial router with built in hardware firewall and hope it has a two-way firewall too. or do I need a separate software for this 2-way firewall, and if Yes, could u please suggest one of those best practices ones',  as I have not come across this before.

Thank u.

In response to John, My provider is Verizon DSL, and their tech support are doing research, but all they know at the moment is that the modem then has to go on "bridge" mode.  Of all the modems, which brand will do an excellent job of preventing intrusions.
What about If I just use software like ZoneAlarm as It is a firewall program I think.
Thank u.
