Are you referring to a Wireless Access Point?  If so, this is a device which contains a radio transmitter and receiver for the wireless network type you are using, and a method which converts that wireless network format (such as 802.11a,b,g or n)  to a cabled network format (such at Ethernet over copper wire or optic fiber cable).

A wireless interface is a device that is installed in / connected to your computer and enables it to participate in a wireless network.  Is is basically a network card which talks to a wireless access point via radio signals instead of to a switch or other device via wires.

"Cisco Wireless LAN Controllers are responsible for system wide wireless LAN functions, such as security policies, intrusion prevention, RF management, quality of service (QoS), and mobility. They work in conjunction with Cisco Access Points and the Cisco Wireless Control System (WCS) to support business-critical wireless applications. From voice and data services to location tracking, Cisco Wireless LAN Controllers provide the control, scalability, security, and reliability that network managers need to build secure, enterprise-scale wireless networks-from branch offices to main campuses."

if we have Cisco Wireless LAN Controllers , do we need the regular PIX firewall?

it sounds like it does the same thing but for wireless devices.

I would have thought you would need both.  From my reading, the Wireless LAN controller provides functionality only to the wireless network (authentication etc).  A PIX Firewall sits between two networks, such as your network (which may incorporate a wireless network) and a public network like the Internet.
