Yes. For track use, a cooler is a must-have. For most DDs, it's just something else to brag about and possibly have problems with. But if sized/installed properly, it won't do any harm.

200F is well within the operating range of most modern oils. The car will go into limp mode (260F, IIRC, FSM will have the correct figure) before the oil gets too hot. Unless you are getting to 240-250F and staying there for extended periods, I wouldn't worry about it - not because of the oil but that means the engine is running a little hot. On paper, modern synthetic motor oils are good up to 300F for extended periods.

Probably the former ... unless you and/or the car look like the latter might apply. It's a common enough mod that it shouldn't raise any red flags.
