1. Do you have to demonstrate your capacity to use UR Special ? in the coaching room, or just when you want to use it?
No, you don't need to demonstrate the capacity to use the UR Special. Just turn one in when you want to use it.
2. Can you use more than one UR Special ? (This seems perhaps too good with bracers of the quivering palm).
Sure you can! If you've really got that many UR Specials to spare! (FYI: Boss monsters are usually immune to death effects though).
3. How will the sub-class saving throw bonus be calculated? If you can't tell us that, will things that grant "+1 to saves" grant +1 to the sub-class? Can you use Figurine of Power: Scarab/Cat on the sub-class save?
Sub-class saving throws usually (but not always) default to a normal saving throw.
So Death, Disease, Poison, and Petrification are sub-classes that utilize Fortitude.
Falling is a sub-class of Reflex saving throws.
Charm, Dominate, Fear, and Illusions are sub-classes of Will.
Broader categories (which tend to be Fortitude or Will) may include Gaze and Undead touch attack sub-classes.
Or does sub-class just mean "one of reflex, fort, or will" and you're not telling us which it is?
For spoiler reasons, I won't announce ahead of time what the sub-class will be, but it will be made clearer at the time of your event.
4. For the AOW effect, do you still get a free action in both the round you get the extra action, and the round you don't?
Yes, you still get a free action the following round but not your standard action. So:
Round 1: Standard action + free action + an advance on next round's standard action
Round 2: No standard action (used the previous round) + free action
5. For the AOW effect when you say "...a player may take another standard action":
* is this any player, or the player who is under the influence of the AOW who has just taken a standard action?
The player under the influence of the AoW.
6. Is the AOW effect usable (or not) each round? Or is it 1 per room or 1 per dungeon?
It is NOT limited to once per room or once per dungeon.
Assuming that you have a standard action every round (i.e. you do not get a status effect that prevents you from acting), then you can use it every other round. For example:
Round 1: Take two standard actions
Round 2: No action (used in Round 1)
Round 3: Take two standard actions
Round 4: No action (used in Round 3)
Etc.
