How do I set up a home network?

I recently got a Netgear 108 Mbps Wireless Firewall Router along with a RangeMax Wireless USB 2.0 Adapter so that I could use the internet on my other computer. I was wondering if I could network the two so that I could share files on my computer, play networked games against friends, and share printers? How would I do this and does it matter if one computer uses Windows ME and the other uses Windows XP with SP2?
