Coil on plug is exactly what it sounds like.... modern automotive ignitions have moves away from a single coil and distributor set up, as well as multi coil packs, and have moved towards "coil on plug" i.e. theres a coil built in to the spark plug "boot" and does away with the need of high voltage spark plug wires that wear out.
As for oil.... thats a whole nother can of worms....LOL i would say go ahead and run the syn... but i am also a fan of a hard break in technique, vs the long and slow 500-1000mi techniques that some use... 99% of the stuff thats gonna "break in" has done so in the first 30 miles (all my opinion, i dont have scientific backing on hand, but i am a mechanic, and have over 10,000miles of trouble free running on my Roketa db07a that had hard break in...)
