Okay I have a straightforward question. Can the critical effects from cards stack? For instance if you get two of the same card and they force you to take 1 point of damage from moving do you then take 2 points of damage? As a follow up is that a point of damage to the hull or a shield (providing there are shields to take a damage) If its in the rules I'm not finding it. Thanks in advance!

I would expect that duplicate faceup damage cards (or damage cards with overlapping abilities) stack. So you would take two points of damage in your example.

I also think that when a card says damage, it is a point of damage that can be absorbed by shields. When they mean hull damage, they specify a damage card (either faceup or not). If the card doesn't specify a hull zone, you are allowed to choose any hull zone (RRG page 4). And in your example case, since it's two separate cards, it could be two separate hull zones.
