Alright, here's my first attempt at a helmet, it came out pretty warped, and even though the helmet fits fine, I wouldn't be able to put padding in as well, so I'm redoing it slightly larger.
I started out pepping this with using my knife to score all the folds, so a lot of them came out uneven, which compounded into the errors seen. I built in this order: Right Jaw, Left Jaw, attached both to muzzle, Right Ear, Left Ear, back, top right rear, top left rear, mohawk, brim, top right front, top left front.
So with the second helmet I spent several hours scoring using pens. Thanks to advice from AI Blue Fox I'll be starting on the muzzle first, and building out from there.
Helmet Numero Dos:
Dos resined and fiberglassed:
Then I scaled and pepped a low definition chest piece to double check sizing:
And completed the HD chest:
Fiberglassed ab plate:
Currently working on fiberglassing the chest! Once the chest is complete I'll be working on the biceps.
Electronics:
Helmet fans:
http://www.digikey.com/product-detail/en/F410T-05LC/563-1130-ND/1165524 5V, low dB, decent airflow, I'll likely use 2 of them.
Edit: Found a better fan:
http://www.digikey.com/product-detail/en/FAD1-06025BBLW12/Q620-ND/2600074 5v, under 20 dB noise level, over 13 CFM, and only 0.40 W running power. It's also significantly cheaper than the other fan.
Helmet Flashlight LEDs:
http://www.digikey.com/product-detail/en/C503C-WAS-CBADA151/C503C-WAS-CBADA151-ND/1922946 3.2V, 28150 mcd, 15° viewing angle, 2 of them directed straight forward on the helmet. Might be too bright.
Helmet/body glow LEDs:
http://www.digikey.com/product-detail/en/C535A-WJN-CS0V0151/C535A-WJN-CS0V0151-ND/1956549 3.2V, 1885 mcd, 110° viewing angle, spread out on body where people typically mount their little glowy bits. I'm not positive that I want them yet, as it seems somewhat counterintuitive to what I want my build to end up like, I may go with no lights, or very dim glow lights.
I'm not sure what I'll do for body cooling yet, I've been working on a water cooled design, but it kind of depends on the undersuit I end up using, and I'm still working out the... kinks... If I can't get that figured out I found some awesome high CFM fans that I can mount in the chest to pump air through it:

But it also draws significant power, so batteries may become an issue. I also need to measure various parts of the chest and figure out where I'm going to mount them so I can decide which size fan I'm going to use.
I'm also considering wiring in a PA type system into the shoulders, but I need to do some further research on the power requirements and just how loud I can make it. At the same time I don't want to have to wear an extra 50 lbs of batteries just to power all this stuff. Compromises everywhere!
Latches:
Ok, here's the latches I think I'll use on the lower portion of the chest piece.

Almost $11 each is kinda pricey, but I haven't been able to find any other powder coated options..
I'll use something similar, but cheaper and not as bulky looking for the upper clasps.

Visor:
Couple options here. I think that I want a mirrored blue visor based on the paint scheme I want to do.

Also, there's this helmet liner:
