Looking for Power Consumption Estimates

I am beginning to plan my electrical system and making decisions between the main bus and endurance bus per Bob Nuckolls recommendations.
I am looking for estimated power usage that someone has surely documented.

Garmin 430W
Creative LED nav lights
Whelen 550 tail light
:

I thought I would see if someone has maintained a list of the many electronic items that would allow me to start estimating.....
Thanks...

Red Creative LED - mine draws 0.193 A
Green - 0.304 A
White Tail Light - 1.725 A (light only, no strobe)
My 430 is not WAAS.

You will find creative power consumption in creative website. If I recall, they are approx. 0,1/0,2 amperes. It depends on the colour (green/white).
You can also find list for devices power here http://www.verticalpower.com/documents.html and here http://www.aeroelectric.com/PPS/Load_Analysis/
