Over 6 years since the arrival of 3e, and I still don't completely get how to mechanically apply the Hide skill. For example:
- How often is it rolled when a character is moving?
- What if I'm moving through shadows (with a normal move of 30), but stop every 50 feet and wait a minute. How often do I roll Hide?
When do you make the PC roll? Whenever it feels right to do so. You don't want to make them roll every round of movement. That takes too long. I make them roll when they initially hide and when they make a significant change in what they're doing while hiding (like moving at a different movement rate or attacking). Otherwise, I try to keep the pace moving without bogging down in rolling.

- If I'm being observed by person A, but not by person B, can I just use Hide against person B? (Logically yes, according ot the RAW, I have no idea).
Absolutely you can if you also have cover or concealment or some other ability that allows you to hide in plain sight if neither of those conditions is met.
SWAT said:
- I can use Hide if I have cover. Makes sense. I assume I duck down or move behind the cover, and thus I can't be seen. But if that's all I have to do, why do I need Hide? Can't I just say "I duck behind the cover."
True, but it's not a very interesting case. Hiding is mostly for use when the character could potentially be seen, and you can't when behind full cover. You can, however, when you're peeking out from behind cover (having now only partial cover) or when concealed. That's when hiding becomes interesting and worth the die roll.

- I duck down behind a low wall during combat and Hide. There's nothing back there to hide me other than the low wall. An enemy walks behind the wall. Does he automatically see me, or does he have to roll Spot?
- Corollary to above question: I need cover or concealment to Hide, but do I need them to stay hidden?
Once he walks around the wall, you're out in the open and he doesn't need a spot to see you. That's why you still to hunt for cover or attacking just as he's coming around the corner. Ambushers don't wait until their hiding places are fully explored to make their attacks. Timing is important.

- Finally, if I Hide during combat, am I treated as being invisible towards the next person I use a melee attack against? At what point, if any, would the target of my attack receive a Spot check?
I treat attackers who successfully hid as invisible. The invisible condition is defined as being visually undetectable. When you have successfully beat someone's spot check, until conditions change, you are visually undetectable. It means, mostly, that you cause your opponent to lose their Dex bonus to AC which, in turn, make sneak attacking possible.
WotC, in Complete Adventurer I think, said that hiding attackers should treat their targets as flatfooted. It's a very similar end result, but one that I think blurs the definition of flat-footed more than the definition of invisible. So I still use my interpretation.
One interesting note: If you treat hidden as invisible, the hidden character cannot be targeted by AoO. If you treat hiding as causing your target to be flat-footed, if he has combat reflexes, he still has the power to AoO you... even if he can't see you... somehow.
