Me no understandy. So you are connected to the WAP, but you can't surf is that what you are saying? Then something must be amiss with your (software) firewall on your machine. I would open up kmyfirewall and load a firewall rules that is totally permissive by default (you are behind a hardware NAT firewall afterall no?). See if that works for you. I used to run into this issue with firestarter, like a year ago when I was struggling to get it configured right.
Good job getting things working, I know how it feels, when things finally start to work for a change. You are almost there, don't give up yet!
