Linux Networking: ICS, File & Print Sharing, Windows

i have two computers networked together via two NICs and a crossover cable. both computers have the following OS installed: Linux (RH7.1), Windows Me, and Windows 2000. (i use LILO)

here's what i want to do: i want to be able to network both computers to do ICS and File & Print sharing.

i'm familiar with Windows, so i had no problem setting up ICS and File & Print sharing between WMe to WMe, W2K to W2K, and WMe to W2K. now, i want to be able to do ICS and File & Print sharing between linux to linux, linux and WMe, and linux to W2K.

i'm new to linux with very limited experience and knowledge on it. as a matter of fact, i just learned the basics last week. that's why i decided to install it on my system so that i can learn a little more. i'm still at the point where i'm still trying to familiarize myself with the GUI (KDE/GNOME).

please explain the linux part in layman's terms. i'll need step by step instructions.

thanks.
