You must move at least one space and may spend up to 7 movement points on Phase A, choosing how many to use (unused points are lost); however, locations marked with the "cannot be skipped" symbol force you to end your movement when you reach them (you may otherwise skip unmarked spaces if you have the movement points). (page 4)

No — a city action consists of two parts (deliver a good, then perform the city's effect) which you may do together, but assistant actions are a separate main action and you can only perform one main action per turn, so you must choose between the city action (including its delivery) or the assistant action. (pages 4, 5)

You get one village action normally, two if you spent 4–6 movement points, or three if you spent all 7; for each village action you may choose option A (discard hand for doubloons), B (take 1 doubloon) or C (buy a card), and you may repeat options across multiple village actions (so you can buy multiple cards if you have multiple village actions). (pages 4, 8)

By default face-up cards cost 1 doubloon each when taken during Phase C; only if you have completed the specific ship upgrade shown on your board may you take face-up cards without paying. (page 5)

Each combat point you spend or each figure you return to the supply increases the current combat value by 1 (letting you perform more combat actions), but combat actions reduce that combat value and you may never reduce it below 0; also you can never have more than 8 combat points on your combat track (excess is not gained). (page 6)

Homeward bound spaces cannot be skipped and have specific effects: space 20 lets you fight or move the explorer, space 21a/21b scores 3 VP and triggers interim scoring at the end of that turn in rounds I–III, and space 22 scores 5 VP and triggers final scoring (game end) at the end of that turn.
