Will Hezbollah Take Part in the Gaza War?

Good question. One way to look at it is to assess their actions. One doing this would note that with the exception of three rockets fired last week - which caused no damage and they responded to by saying they weren't behind firing them - they haven't said a peep except an occasional, obligatory statement that invading Gaza is bad. And that probably means they really aren't looking to get in on the Gaza fight or cause more trouble.

The other take is to just make up hypothetical intentions based on the principles that "Israel is good", "Iran is evil", and "everyone in the middle east is a wholly owned Iranian subsidiary". In this world we assume Hezbollah omnipotence and omniscience and so if a rocket was fired they must have at least ok'd it and since they haven't done anything since that clearly means they are just planning and waiting. And since it is only a matter of time before Iran unleashes them we should bomb Iran now.

Note to Israel, paranoid and delusional analysts are not your friends.
