Scoundrel/Operative DPS Compendium

[Storm]

Hey there. I was searching the forums but couldn't see if this had been adressed already. The Vibroknifes have something in their tooltip saying that this (offhand-)weapon is only be used by some abilities. While logic suggests that these are only the knife-related skills, I'd like to know if there is currently any source where I can search for formulas backing this theory up and - more importantly and I hope those who are already deep in the numbers can answer that - where exactly do I get the formulas that are responsible for ability damage enabling me to see which factors are counted into the damage calculation of e.g. Shiv. Are there any at all? Because most of the datamining-networks like TORhead and KnoTOR haven't their formulas up yet.

And lastly, my most frustrating search I've done before asking: Is there any estimate on the damage absorbed by Shield Probe in numbers?
