Hello,
I have infared installed on my laptop. Do I still need a wireless network card? What is the infared good for?

Ir is for connecting to PDA's and Cellphones etc that have Ir. I can synch my PDA to my laptop, connect my cellphone modem to my laptop using Ir.

Infrared is not Wireless. Its an invisible light beam, that works up to a couple of feet or so in direct line of sight.

The light beam is in the Infrared part of the spectrum, which is why its so called.
