First things first, in order to send/recieve information over the internet or a network your computer must know what type of information/command it is. This is where ports come into play. All information send and recieved by your computer has a specific port ID number associated with it. One example would be HTTP traffic (web surfing) which uses port number 80. The ports identify what type of information is being sent or recieved. That being said, below I put some rough definitions of the technical terms you mentioned. Its not too important that you know what the abbriviations mean, just as long as you know what they relate to.

[list=1][*] Netbios: This is a commonly used network protocol. It allows other computers to give your computer commands or messages. Your firewall probably blocked it as a safety precaution.[*] TCP: This is an information exchange protocol. Most forms of internet traffic use this. When it says TCP traffic was blocked it probably means your firewall has a built in pop-up blocker. You can disable this in your firewall options menu.[*] UDP: (outgoing): This refers to information being downloaded from your computer by another person. This is common in filesharing programs such as Kazaa or WinMX. The firewall blocked it as a precaution (it doesn't know if the person downloading stuff from you is a hacker or not).[*] ICMP: Mostly known for the Ping command. Some ISPs and websites will ping you to see if your still there. The firewall blocked this because pings, while mostly harmless, can be used in attacks on you computer. [/list=1]

As for whether or not this is bad or good: it depends on what your doing. If you are using programs that make use of the internet (ex. Kazaa, AIM, or certain games) then you want to look up in the manual or help section of your firewall on how to give these programs unrestricted access. Its usually a list you simply add the programs to.You might also want to check the security level setting of your firewall. This is usually high, medium, or low security level. Its best to set it at the medium level. This will block most malicious traffic while not being a pain in the butt. Last thing, those messages you recieve about whats being blocked, can usually be disabled in the options menu. The firewall will still work, it will just do everything in the background instead. I hope this is of help to you.
