Clark is going to be REALLY confused by the comics, especially things like the whole Death of Superman story arc. And the whole "marriage to Lois" thing he'll find has to be fairly weird too.
He probably doesn't know about Wikipedia if he's from a few years in the past - if he goes on line he may not even know Google, assuming that either will actually exist in his universe - and the most famous news service, LNN, won't be there either. He may even get the idea that the world has gone wrong because Lex isn't there, if he doesn't know better.
Meanwhile Lois probably knows a lot about Superman and her fictional alter ego... but most of it will be wrong.
Greatly looking forward to more.
