So if a legitimate program wants to call home Win7 firewall is going to alert me? If so thats a major upgrade from past versions. which is good.

Ever hear of a driveby infection through the browser..no action on your part needed..had it happen once...came through port 80 from an infected news site...fun stuff
No, Windows 7 will not block 'call home' software that is signed (via legitimate third party or Microsoft). Windows 7 will warn you about unsigned [Usually older] software if you try to install it - in which case, if it does want internet access, Windows 7 will ask you if you wish to allow it through. It isn't the safest methodology, but it's far less intrusive than more professional software/hardware which wants to make rules about every type of port activity (common end users would be ripping their hair out
).
Also, most firewalls will not block anything coming over port 80 (or 8080) because it doesn't know good from bad - all it knows is port, yes and no. Your antivirus software should be scanning open ports for bad data (that isn't encrypted). Many AV packages now include web, email and other common ports for malware.
Windows 7 now comes with multiple layers of protection, most of which are beyond the scope of this thread. However, the key thing is that it knows the difference (if you answered correctly during setup) what type of network you're on and how much security to enable. If you are paranoid, go with Public Network vs Home. It will close off many common ports and enact rules that will prevent the majority of threats that exist out there. Doing so will involve some tweaking if you use things like torrent downloaders, some games that use odd ports and perhaps an app or two. Enabling Public will also kill many network functions of which you'll have to enable yourself later.
Like I said, get Comodo if you want a more advanced firewall. It's overkill really, but if you share large networks (colleges for instance) and know what you're doing (getting Windows services to work through a firewall if you do exist on a large network), then go for it. For me, ZoneAlarm is a bit twitchy. It's a PITA if you want to use some software packages or you have third party software that wants access to the TCP/IP stack.
