Thermostat Replacement Help

Click for full size
I'm trying to change out my old Trane Weathertron Thermostat with a Carrier Thermostat. Below is the information I know about both (which isn't much):

Trane Weathertron Baystat239A - Currently there are eight wires hooked up to this thermostat. Those wires are below with my understanding of what each of them are based on looking through the web.
X2 - Emergency Heat
O - Switches the heat pump from cooling to heating
G - Fan
Y - Compressor in both heating and cooling
T - Outdoor temperature compensating thermostat sensor
R - Hot power
W - Aux heat
U - No wires connected
F - No wires connected
B - Common

The thermostat I'm replacing the Trane thermostat with is a Carrier Comfort Series Non-Programmable (33CSCNACHP-01) thermostat.
Rc - 24V Cooling equipment
Rh - 24V Heating equipment
W/W1 - Heating
C - Common
G - Fan
Y - Cooling
O/B - Reversing Valve
Y1 - Not used

Can anyone help me figure out what goes to what? I obviously have very little idea about these but I'm remotely handy so I figured I could replace it myself...Any help is greatly appreciated.

Specifically which wires are you unsure about?

Really what goes to what. I know the Common goes to Common and Fan goes to Fan but beyond that I'm unsure.

Post a pic of the wires where they connect to the furnace and also the furnace model number.
