I like having Zone Alarm to warn me when programs are trying to phone home / request for updates etc.

However, I feel its interface is a little clunky and was wondering if there are any alternatives out there?

I'm running Windows XP.

Try Comodo Firewall, it is free, has a 64 bit option and a training mode so you can set it up with your programs quickly and pain free.

Sunbelt Personal Firewall and Jetico Personal Firewall are both very good and very configurable. Although I find the Jetico documentation to be a bit lacking.

Sunbelt is gone: After many years as leader in firewall protection, Sunbelt Personal Firewall is being discontinued. – stivlo Nov 14 '11 at 17:07
