1). Correct. You do not need to sleep.
2). Correct. Though I'm guessing True Resurrection, Wish and Miracle are still options.
3). It's not marked as Evil as such. So I'm guessing it's like any other form of violence: not Evil when warranted or inflicted upon the deserving.
4). It seems doubly-iconic for this character to be hopping a lot, so I'd put some emphasis on that in your RP.

Regarding point number 2, if I'm not mistaken, you would lose the undead template/associated powers and just come back as a regular grippli...
An "odd turn of events" is a very big understatement.
You seem to have lost two levels, but that doesn't matter, you are vastly more powerful than ever before. If you're gaming with other level 3 characters, you will be like a god amongst them. I hope your GM knows what he's doing...
As for answering your questions:
1. Yes. See below.
2. "Scatter" is not a game term; it's up to your GM to determine just what it takes to scatter your dust. Me, I would say that it takes at least the same amount of effort as mixing it with rice and holy water (or else why would anyone do this if they could just blow on your dust and solve the problem?)
3. No. It's a tool, like using a sword or casting a fireball. It's not the tool that determines the alignment, it's the way you use it - if you use it for good purposes (killing bad guys, protecting the innocent, etc.) then you're committing good acts, but if you use it to kill innocents and commit crimes, then these are evil acts. By comparison, the Enervate spell and the Vampiric Touch spells do not have "evil" descriptors.
4. Watch out for your party's cleric...
An undead creature possesses the following traits (unless otherwise noted in a creature's entry).
No Constitution score. Undead use their Charisma score in place of their Constitution score when calculating hit points, Fortitude saves, and any special ability that relies on Constitution (such as when calculating a breath weapon's DC).
Darkvision 60 feet.
Immunity to all mind-affecting effects (charms, compulsions, morale effects, patterns, and phantasms).
Immunity to death effects, disease, paralysis, poison, sleep effects, and stunning.
Not subject to nonlethal damage, ability drain, or energy drain. Immune to damage to its physical ability scores (Constitution, Dexterity, and Strength), as well as to exhaustion and fatigue effects.
Cannot heal damage on its own if it has no Intelligence score, although it can be healed. Negative energy (such as an inflict spell) can heal undead creatures. The fast healing special quality works regardless of the creature's Intelligence score.
Immunity to any effect that requires a Fortitude save (unless the effect also works on objects or is harmless).
Not at risk of death from massive damage, but is immediately destroyed when reduced to 0 hit points.
Not affected by raise dead and reincarnate spells or abilities. Resurrection and true resurrection can affect undead creatures. These spells turn undead creatures back into the living creatures they were before becoming undead.
Proficient with its natural weapons, all simple weapons, and any weapons mentioned in its entry.
Proficient with whatever type of armor (light, medium, or heavy) it is described as wearing, as well as all lighter types. Undead not indicated as wearing armor are not proficient with armor. Undead are proficient with shields if they are proficient with any form of armor.
Undead do not breathe, eat, or sleep.
