Honeywell Prestige HD thermostat wiring 1H/1C + Humidification System
 
Let me start off my saying that any help would be greatly appreciated!

I recently purchased a
Honeywell Prestige HD YTHX9321R5003 Deluxe Comfort Thermostat System Kit and need some advice on wiring it to replace both a thermostat and humidistat. I have an electrical engineering background and I would rather install it myself and not have to pay for a service call.

I have 6 wires coming from the furnace to the thermostat and humidistat (wires: red, green, yellow, white, blue, orange) (see details below). Since I want to replace both units with the Presige HD, my questions are:

Do I have enough wires?
Do I need the Honeywell THP9045 Wiresaver Module?
Do I need to change any of the wire connections at the furnace for the humidifier control?
Which wire do I use at the Prestige HD for C? orange?
Which wire do I use at the Prestige HD for U1 (humidifier relay)? blue?

Here is my current setup:

AMERICAN STANDARD FREEDOM 80 FURNACE (GAS) + AMERICAN STANDARD AIR CONDITIONER + LUX 500 THERMOSTAT

POWER: red wire: RH (at thermostat) -> R (at furnace)
RC (at thermostat) -> short black jumper -> RH (at thermostat)
FAN: green wire: G (at thermostat) -> G (at furnace)
COOLING: yellow wire: Y (at thermostat) -> Y (at furnace) -> red wire (to A/C unit outside [compressor])
HEATING: white wire: W (at thermostat) -> W (at furnace)
C (at furnace) -> white wire (to A/C unit outside [compressor])

APRILAIRE 760 HUMIDIFIER + APRILAIRE 883321B HUMIDITY CONTROLLER

red wire (at humidifier) -> blue wire (at humidistat)
white wire (at humidifier) -> 24V Transformer (yellow wire) -> 24V Transformer (other yellow wire) -> orange wire (at humidistat)

Here is the wiring info for the Prestige HD:
Honeywell Prestige Thermostat Installation Guide (refer to page 4-7 for wiring info)

Here are some pics of my current setup:
