There isn't AFAIK. It would be possible but it's probably not worth the effort. Once you start understanding how d2 stuff works, you can make out most of the skill mechanics by using it and reading the short description. For everything else usually a couple posts in this thread suffice.

AFAIK VoR and VoJ cast up to their number of blasts to the creatures in their range. So in the case of VoR every 0.05 seconds up to 5 blasts will be casted. If there are less than 5 creatures in the 3 yard radius, less then 5 blasts will be cast; if there are more creatures than blasts, some creatures won't be hit. The number of potential blasts can be increased with the passive. Special note: if no holy or unholy skill is chosen, both bonuses of the passive apply (this is usually called a neutraldin build).

I'm pretty sure the arrows do damage on impact and the trail is just a nice gfx effect, I'm not 100% sure though.

Poison damage is special in many ways. You should definitely check
here to understand it better.

Generally speaking when a skill is said to "hit multiple times" or "multihit" it means it releases missiles that have a next delay (ND) of 0.
ND is a missile property that starts a timer when a monster is hit. When the timer is active, that monster can't receive damage from the same kind of missile (or every missile? I'm not sure). A missile with ND equal to 0 can multihit, that is, hit more than once in a single frame.
Take hunting banshee: when it explodes it releases a nova made up of 64 missiles. In its first incarnation those missiles had a ND of 0, so the explosion could potentially deal 64 times the listed damage of the skill. Now hunting banshee's missiles have ND (I don't know the exact value, let's say it's 1 for the sake of this example); if a nova explodes on top of a monster, it'll be hit 64 times in a single frame, same as before, but after the first time it takes damage a timer that lasts 1 frame is started; it can't take damage from the same kind of missiles until the timer expires, so the other 63 missiles don't do damage. On the next frame, if it's still being hit by at least a missile, it'll take damage again, once, and so on.
