What happens if I put this on a Specialist when there’s only 1 card left in my deck?
[Source: WotC]
In that case, you’ll scrap that card. Then you’ll shuffle all the other cards in your scrap pile into your deck. Then you may play the card you scrapped. If you don’t, it will stay in your scrap pile.
Full Loadout will put all three upgrades onto
Wheeljack. You then handle all of the triggers in an order of your choosing.
I have
Wheeljack - Weapons Inventor in alt mode on the field. I play
Leap of Faith and flip Field Communicator as my first card. I play Field Communicator and equip it to Wheeljack. With this scenario, does Wheeljack’s ability to draw then scrap a card occur before I do my second flip for Leap of Faith or does it have to wait until Leap of Faith has fully resolved?

EDIT: You must resolve
Leap of Faith and the second card you flip from Leap of Faith, then Field Communicator’s ability and
Wheeljack’s ability can be resolved in an order of your choosing.
Say I have a Field Communicator on a Specialist (Let's say it's Arcee, because why not?). Is it then possible to play a second Field Communicator to replace the first? (In order to re-trigger the effect on a specialist)
[Source: WotC]
Yes.
I have a Torox with
Tooth and Claw and
Mining Pick in his Armor Slot, as well as Divebomb with a Field Communicator. If I combine them into Predaking via the
Predacon Enigma, am I required to keep Tooth and Claw in order to carry the Mining Pick to Predaking's armor slot, or can I bring the Field Communicator instead?
[Source: WotC]
Once an Upgrade is legally put into a slot, it stays there, even if the ability that allowed it to be upgraded in the first place no longer applies. In your example, you could keep
Mining Pick in Predaking’s Armor slot. Upgrades that are on characters that combine into Combiners are considered to stay in their slots, even though those slots now belong to the Combiner.
I have a question regarding
Sergeant Cog. When he dies, I place him on
Private Red Heat, and Trigger his ability. Let’s say I draw 2 cards. I can then upgrade each of my characters, and let’s say I play Field Communicator on one of my specialists from the Cog trigger, do I resolve Field Communicator’s trigger before finishing the last Cog upgrade trigger, or do I finish the Cog trigger, and then resolve the Field Communicator trigger?
[Source: WotC]
Finish the
Cog trigger completely, then resolve any resulting triggers like Field Communicator in an order of your choosing.
Are actions played with Field Communicator set aside like actions played from a hand, or do they remain in the scrap pile?

They are set aside like actions played from a hand.
