All scenarios are wrong because there is no "rouge" class... ;)
Kidding aside:
1st Scenario: On his next turn he breaks invisibility how? Dismissing an effect is usually a standard action which won't let him make any attacks (he used his only standard action to dismiss invisibility). The easiest (and probably best) way for him to dismiss invisibility is just to make an attack.
(Side Question: if the enemy is still flatfooted in round 1 because they have not moved yet, then your rogue may sneak attack with every attack and he doesn't even need to use Vanish - this is because Flat-footed combatants lose their DEX modifier until they are no longer Flat-footed, which makes them able to be sneak attacked)
2nd Scenario: Nobody can make any full attacks in a Surprise round. You can only take one Standard action or one Move action, not both, and no Full-round actions. So, during the Surprise round he can take one attack and use Sneak Attack. That's it. Then during the first (non-Surprise) round, if he has higher initiative, he can take his Full Attack action and use Sneak Attack on every attack because the enemy is still Flat-footed. If the rogue loses initiative, then during his first (non-Surprise) round, he cannot take any sneak attacks because nobody is Flat-footed.
If in the 2nd Scenario the rogue wants to snipe, he must begin with concealment (in your example he did this) and then every round he can try to snipe - one shot that allows Sneak Attack, then the Stealth check at -20 to resume hiding so he can try another snipe shot next round.
Since we're discussing Ranged attacks, don't forget that the rogue must be within 30' to use Sneak Attack.
"For this one, only one, his first attack, he gets the benefit of being invisible (target loses DEX modifier, rogue gets +2 to hit and may sneak attack). Now he is visible BEFORE he makes his second and third attacks. So he only gets sneak attack on his first attack".
Do you have a quote from the rules that shows this?
Have not been able to find anything in the invisibility spell regarding it. If you can get full attacks when the enemy is flat-footed, I don't see why you wouldn't be able to if you are breaking invisibility with a full-round attack action.
