Cisco 2600 Access lists & Priority lists

I have a Cisco 2621 and I'm trying to get a few things working on a router/network that I play around on.

First, I'm trying to connect to a Battlefield 2 online server. I know the problem in somewhere in my access list, 'InternetIn'.  When I add 'permit ip any any', the game will see all servers no problem. But that's not how I want to handle it. After I did that I went to GRC.com, did a stealth check and it was able to see all ports. I don't want that. I'd rather close every port not needed. But the problem is I can't figure out how to make it work with 'deny ip any any'. How can I modify my access list to make it work while being as stealthy/secure as possible? Also, can someone help streamline my access-list if I have useless stuff in there?

Second, I have several machines connected to this same router. But I want to give the gaming machines priority [high], web servers priority [medium], internet surfing machines [normal], etc... So I setup priority-list 1 default high and access-list 1 with only one machines ip address '192.168.100.44'. Will this machine have priority over the rest? Do I have the right idea here, or should I change something around? Maybe an example of different machines with different prioritys...

Hopefully next week, I'll get around to installing the advanced security IOS. Can someone point me in the right direction for settings I should look into?

Here is the config:
