Linking PC and IMac for Internet and File Sharing

Laptop (XP Pro) hooked into BT Business Broadband, using BT 220V ASDL Router and USB connection, working fine.
Want to link to IMac, for internet and file sharing, using the Ethernet ports on each machine. Assume I will need a crossover cable?
After that I am stumped. Can anyone point me to simple guide as to how I might achieve this link?
I have examined other posts on similar subjects without much joy - possibly because I know nothing about Macs.
Thanks
