Wired and wireless network in harmoney?

Hi there peeps, My question is I have 4 desktop pc's and 1 laptop and i am setting up a LAN arena for some gameing action, at the moment my setup is 1 main pc with broadband comming through a motorola sb5100 cable modem conected via usb 2, this pc is then conected to a netgear Wireless access point ME102 via Ethernet cable from pc network card to WAP ethernet in port. the other machines all have qtek wireless network cards and so far this seems to work but now my freinds are asking if they can bring there custom cased, pimped up, overclocked rigs and guess what? they cant afford wireless cards cus they spent all there money on dremels and thermal paste !!! I hav a 5 port Switch and was wondering how to wire it to my current setup. any info would be great peeps.

Plug the internet-connected machine in to the switch, then plug the WAP in to the switch. Easy....may take a little configuration changing, but not much.
