Firewall/Windows 7

Is there any need to use Comodo’s firewall as 7 has it’s own, & would the two interfere with each other?

Windows 7 firewall has limited outgoing protection on its own, if you like control of whats flowing out of your computer it`s better to use Comodo.
If you do install it may not switch off windows firewall so be sure to turn off via Control Panel/Windows firewall/turn windows firewall on or off.

Action centre should look like this.
