You use it before the game begins. After you put the
Medic! into your hand, you’ll shuffle the rest of your deck. Then you’ll draw the normal 3 cards at the start of the game. This means you’ll start the game with 4 cards in hand (Medic! plus the 3 you draw). You’ll still draw a card at the start of your first turn.
If I move damage counters from one of my characters to another character, will Specialist Ratchet’s ability trigger?

No. Moving damage counters is different than repairing.
If you play
Salvage for Parts while Specialist Ratchet is in bot mode, and you scrap, say, 2 opponent upgrades along with yours do you get to use the repair for the opponents scrapped upgrades as attack for Ratchet?
[Source: WotC]
For
Salvage for Parts, you’re doing all of the repairing, so Ratchet’s ability will trigger that many times. In this scenario, that would give Ratchet +4 Attack.
Say Specialist Ratchet (In bot mode) got a +3 attack bonus from his skill, and then flipped to alt mode. Would that +3 attack carry over into alt mode for the turn?
[Source: WotC]
Yes.
Before the game starts, find their related card, shuffle, then draw three cards for your opening hand.
