Problem with Permissions/Firewall

I will start off by saying that I run mandrake 9.1. One day I decided I would secure my machine sence I had everything running from root with no firewall. First thing I did was make a new user called 'slick', his main directory is /home/slick. Then I moved all the folders of the programs I use from the root folder to /etc folder. I changed the folder permissions to slick. Be aware I am doing this all with teh GUI. After that I turned the firewall that it came with on, and opened up the ports that the programs use. Now for the problems


When I try to log into slick via the console it says

-bash: /etc/profile: Permission denied
-bash-2.05b$

Then I just type log out and it goes back to where it was before. I usually just log on root and log off and it then lets slick log on for some reason. Whats up here.

Now for the programs. Ventrilo server, BNC server, and tuxtime work without any problems but Folding@home isnt so nice. When I do manage to get slick logged on (It works sometimes, i dont know how i do it) it will not grab a work packet. I know it has before but it refuses to get a new one. I though this may be a firewall problem but I have the correct ports open, could anyone tell me what the right port is just to make sure.

Thanks in advance.
