I have an older eMac. I would like to connect it to my wireless network. Does it come from the factory with wireless? (Been in the basement unused) or could I buy a card/usb networking card? Is there such a thing as a USB wireless connection?

yes there are USB wireless a/b/g dongles.

here is a newegg search page Newegg.com - Wireless Adapters, PCI Adapter, Wireless-G Adapter, Wireless-G Network Adapter, PCI Wireless Adapter, Linksys Wireless Adapter

it won't set you back too much

If you prefer to go the Apple route, the very first eMac had a slot for an Airport card, the rest could take Airport Extreme. There are plenty of the latter on eBay these days.
