Tolman, unless what et voilą says about ISP choking P2p and such is true (for you), then try the following: as your upload speed is 128kbps, set the meter between 10,48 and 12KBps, put (for starters) 10 upload slots and increase the number of simultaneous dlds to 25. Now, look for a file that is popular enough and dld it: stop any other dlds and dld just that one file. Give it some time to connect to the other peers.  
I hope that this makes a change.   
btw, I had no idea that OSX 10.3.4 has a built-in firewall (like XP)... Well, well, we learn something new everyday...
