You need to activate FTP server on your computer and remove anonymous
FTP access to avoid that anyone can get in. And ofcourse use a long
password on the user that may access the the FTP user. Please note that
you will get very often dictionairy attacks on your FTP server.

I would suggest to use vitual folders (directories) in your FTP server
to share folders that are located on other computers. I'm not sure of
the Personal FTP server from Windows XP does that. The Windows server
version does that.
At least the FTP server will need a IP address on your local network
that does not change (either fixed or maybe you can specify in the
Linksys router that MAC address x always get the same IP address.

Then you need top open up your FTP port 21 for incoming trafic on the
Linksys Router and map it to the IP address of your FTP server.

You can share all of your computers if they have all an FTP server if
you can do port mapping on the Linksys router. This would mean that you
would access for example port 7322 from the internet and map it trough
the Linksys to port 21 of that specific computer.
This would mean that every computer has it own public port.
I STRONGLY ADVICE AGAINST THIS!!!
Opening up all you computers to the internet is a serious security risk.
IT IS BETTER TO OPEN UP 1 FTP SERVER, USE VIRTUAL FOLDERS AND MAKE SURE
THAT ONE COMPUTER IS ALWAYS UP-TO-DATE AND WELL SECURED!!!

It is far more difficult to keep x number of computers secure...
