Also, must the character who is hiding roll each round to remain hidden, or only if he does something that might reveal him?
Only when you move while in concealment (or the ST thinks calling for another roll makes sense, or a Charm does it, etc.)
Lastly, on a turn where a hidden character moves in to close range and attacks, do they need to roll to remain hidden?
You would need to roll when you move into close range. After you attack, your concealment's broken.
