As far as communication devices, the maximum speeds typically available are:
Infrared = 4 Mbps (Fast Infrared or FIR)
WiFi
2.4 GHz - 20 MHz-wide = 108 Mbps
2.4 GHz - 40 MHz-wide = 270 Mbps (1 40 MHz-wide channel)
5 GHz - 20 MHz-wide = 54 Mbps
5 GHz - 40 MHz-wide = 350 Mbps (at least 10 40 MHz-wide channels)
Bluetooth
2.4 GHz = 3 Mbps (speeds up to 480 Mbps are proposed)
Bluetooth has 79 1 MHz-wide channels, but the 2.4 GHz b/g/n band interferes with 22 of those.
I guess I'll have to stop researching answers and just point people to wikipedia and google.

Infrared is a visual communication system similar to your TV's remote control. It requires line-of-sight for the two devices to communicate properly.
Wireless and WiFi usually mean the same thing, although they can be different. Some Internet service providers use the term "wireless" to mean a parabolic microwave dish mounted to your house similar to a satellite dish (like the ones used by DirecTV or Dish Network).
WiFi specifically refers to the 802.11x standard and is a network protocol for connecting computers (and some phones) to local area networks. This would be the "wireless" ethernet card in your laptop or desktop.
Bluetooth is a generic protocol that describes how different devices (not necessarily computers) can communicate with each other. Although it is capable of networking theoretically, in practice, it is used by things like wireless mice and cell phone accessories.
