Since then, when it shifts from 2 - 3, there seems to be a little extra shift. If that makes sense. It pulls fine at takeoff, then just before the up shift, it almost feels like it kicks down, then pulls strong and up shifts as it should. It doesn't feel like a slip. It's weird. Also, I'm not sure if it's related, but the shift indicator lights seem to be out of sync. showing an up shift before it actually happens.

Could the shop have used the incorrect fluid? They swear no, but after catching them in a few "falsehoods". I don't trust them. Would the incorrect fluid cause this to happen?

Or am I just being paranoid!

Yes, the wrong fluid can cause the Tip to shift differently, but the fluid would not explain lights. I would have a good Porsche shop re service the trans and look it over.
