============
It may become less confusing after you read how a trojan works, for instance, a trojan
that uses port 6969 http://www.doshelp.com/Ports/6969.htm
Opening a port is dangerous if the trojan that uses it happens to be installed in your
system. As precaution, it's good to avoid opening a port through which a trojan could (if
installed) do its deed.
Opening a port in XP firewall is easy to do, same steps as allowing an application to
access the internet, except you 'Add Port...' instead of 'Add Program...'
If you don't like the idea of opening ports, set WinMX to operate in firewalled mode,
connect as secondary only.

Transfers on WinMX are directly from peer to peer. Servers get involved in searches,
whois and browse basically.

You can't download faster from your peer than your peer uploads to you, but you can
download simultaneously from multiple peers on WinMX Peer Network.

It means only that you have more bandwidth available for downloading than for uploading.

Your computer needs to communicate to the other computers when it's ready to receive more
data. You should allocated some of that 256k upstream bandwidth for such communications.
Use WinMX's Bandwidth Throttle function (in your case, limit outgoing bandwidth to 24000
bytes per second).
