Took the 986 to an independent

Sounds like it's the RMS seal, it will leak oil prior to failing. But it could also be one of several other things, go by an auto parts store and have them read the codes.

Personally, I would get a second opinion from a different shop. Any mechanic that claims to have diagnosed IMS failure before it happens, especially on a '99 which isn't affected by IMS failure is either an idiot or trying to rip you off. I am also not sure why you would need a new clutch for an oil leak.
