Well the source obviously is where its from the destination IP is you.

Most of them are just pings or ppl checking you out.

And unless the port the person is using belongs to a known trojan / worm, I wouldnt worry about it.

And where its got security rule matched, a rule is already in the firewall, which is why it blocked it.

As mentioned above, the entries are merely logging the information that you have asked your firewall to record. If you don't want so much displayed, adjust your firewall settings. Out of interest what firewall are you using? a stand alone or a software firewall? i notice that you have 6881 open - lol, the default port for Azureus.
Don't just assume that everything is ok, attacking and taking control over a machine with ports open is a simple task, and to then overtake that pc, and use it to launch attacks onto other pc's is easy - even without you even knowing. I just finished a lecture from Jesper Johannson - a Microsoft speaker from Tech Ed 2005 teaching all about this sort of stuff.

I advise you to run some port scanners on your machine:
and make sure you only have the ports open that you need.
