I do not know exactly where it is, however I might have a starting point. In this thread:

it gives some numbers which appear to correlate to the different vip skills. If you take Murtah's

You can look inside \c3\effect\ for something that look like those effects. The "skill" folder seems to be the only folder to go to numbers as high as those found in the cq_action for the skills so I would try there. I do not know what all the different effects look like as I never played around with them, but it seems logical that they would be in there.
Edit: Also take a look at 3dEffectObj.ini the files it points at look closer to the pic in the first thread I mentioned.
