Insulating Garage doors- A few options.
1) Some folks have a "bubble wrap" type product installed. I am not a big fan of this method.

2) Some folks go to a big box store and buy the styrofoam or Thermax type panels, cut them and install them.

3) Ro-Mac sells the insulation kits made by Clo-pay, the company who makes your garage door. The R-value here is about 6.2 It does help insulate against the radiant heat and will keep your unconditioned garage cooler.

Cracking your attic pull down stairs-

Will it be a fire hazard? Well, strictly speaking, yes. Understand though that on the homes that have a gas furnace, there is already a air grate in the ceiling, so your ceiling no longer has a fire rating at that point anyway. And those attic stairs most always are only 1/4 inch plywood, which has almost no fire rating anyway.

Understand that garage ventilation and attic ventilation are entirely different subjects.
