Howard,
I'm surprised your anticipated load is going to be so high. My IFR RV-8A only uses about 32A with everything on. I use the 60A Plane Power Alt and it is loafing.
If you are recommending LEDs to be used for landing lights, I'd suggest builders consider HID instead. I have both on my airplane and, as much as I like them, the LEDs are not yet up to the task of landing light. They are great for radiance, but do not illuminate well. The power and optics are just not quite sufficient. I use the LEDs for taxi and recognition lights. They wig wag much better than HIDs and light up using a square wave which makes them visible and discernable at long distance.
The HIDs, although expensive, are excellent for landing illumination.

Thanks I'll add those items. I'm going to go without the cooling fan initially
and see how the avionics fare. I might have to add later.
For those planning IFR w/ similar equipment....it looks like the LC-60 amp alternator
is a must due to the high current consumption of the pitot heat, navigation,
strobe, and landing lights.
For anyone who has not yet purchased equipment you'll want to buy LED style, and
maybe the Gretz Aero pitot heat system to keep the amps down.
I'm going to switch to the B&C LC-60 amp alternator and plan for a max continuous
electrical load of 80-85% or 48 to 51 amps.
