Now that I've got my Firewall etc up and running...how do I know what to "Allow" when AVG asks if I want to let a certain program thru? For example....i keep getting a request to let a 'generic host' Win32 thru and I'm not sure what it is.

There may be a HELP file with your firewall that will explain some of the basic concepts, and there is a good Tutorial on firewalls at BC:

http://www.bleepingcomputer.com/tutorials/understanding-and-using-firewalls/

If your firewall allows you to manage permissions by application, doing so saves a lot of time. Hopefully, your firewall normally gives you enough information to make a judgement about whether some application or program has cause to connect to the internet.
A good rule of the thumb where you are NOT SURE, is to disallow it (not permanently, but just the one time) and see whether something you want to happen happens- - -if not you can redo the task and permanently allow it.
Hope this helps, since I know that teaching your firewall can be quite confusing the first time you use one.

I read the 'tutorial', but I'm still having problems with my security software. I can't figure out how to allow a program to go thru the firewall after I've allowed it to block it once. Secondly, Zone Alarm states that I have no 'antivirus software' running. Doesn't the AVG program have antivirus software?

Yes, AVG is an anti-virus application.
Sorry, I do not use ZA, so I cannot help you with your other question.
