Yes, it does not target, so can destroy Obelisk, and will destroy Ra too if his ATK is high enough.
I'm going to assume you mean Crush Card Virus. How it works is you tribute a dark attribute monster you control that has 1000 or less attack, such as a Saggi the Dark Clown or Yubel, and then you look at all the monsters your opponent has on their side of the field (face up and face down), all the cards in their hand, and all the cards that they draw until their third draw phase after you activated Crush Card Virus and you destroy all of their monsters that have 1500 or more attack points.

As long as you are in the Battle Phase, then yes, you could use Trap Jammer against Crush Card Virus.
Pay an insane amount of money for it...
get a yugioh gold series, collectors pack, open it, then the sub-box in the middle will have crush card virus in it. Return the other mini-boxes, if the store keeper allows.

Sorcerer of Dark Magic has a Quick Effect that can be chained to any spell speed 2 Trap card (meaning he can't stop a Counter Trap). So when Crush Card Virus is activated, he can chain his effect to it. His effect will resolve, negating the activation and effect, meaning Crush Card Virus does not resolve - nothing is destroyed.

You can chain Spell Speed 2 or 3 effects to Dark Hole. Crush Card Virus is Spell Speed 2, so yes, you can chain it to Dark Hole's activation.
