You need one wire/wireless Access Point router.There are other home networking topics at the top of the link.
You need 1 wireless card. You should leave one machine with a wire connection connected to the router.
You should buy a UPS/AVR system to protect your investment. The router likes good clean and constant power and doesn't like power spikes or drainage on the line from household appliances switching on and off all the time and will go defective if it happens on a routine basis. Belkin makes good ones.The above is what is in the link below.
You may want to look into a print server that plugs into one of the router's LAN ports and wire or wireless machines can print to the network printer.
They have setup and install wizards now, user manuals and Tech Support for the router and the wireless card, even the print server.*Learning Center* You should get a router that has logging so that you can watch inbound and outbound traffic to the router with a tool such as Wallwatcher. Duane :)
