The Sinister coolant filter is what I run. The kit is very well thought out and high quality. I highly recommend it.
As stated, flush the system and swap to ELC coolant. The factory gold Ford junk can't take the heat of a Diesel and is badly formulated for Diesel use.
You have the good EGR cooler. If you want to delete it you really should get an aftermarket tune to allow normal operation and no codes. Your year you will likely not get a CEL if the EGR valve is still plugged in, but the soft code can cause other issues as noted.
I would stick with the factory oil cooler system. If you are doing an EGR delete anyway I would advise this: do a coolant flush prior to any work, delete the EGR cooler and install a new oil cooler, install coolant filter, and fill system with ELC coolant. This addresses all the possible issues as once. The screen you note is for the HPOP and sits under the oil cooler. The oil cooler kit from Ford will have a new screen. Suction the reservoir dry, clean everything, and install the new screen.
Oil temp should never get to 240 or above. If it does change the oil immediately. Oil begins to break down at that temperature, and you lose lubricity which can kill the engine.
Ford specs a delta of not more than 15 degrees ECT vs. EOT. if you see more than that the oil cooler is shot. On a brand new oil cooler I see a delta around 2-7 degrees most of the time.
