Dont stress man!! Layering is when you take 2 sound that are "the same" and layer them with the same notes in both patterns! If you have strings in one pattern with 1 vst Add another vst with strings that are in the same soundrange and add those notes to that pattern!
Compressing is alittle harder to explain, Youtube how to use a compresser and that should help alot!
It takes time to understand everything dont get discouraged just keep working at what you want to do and build skill!
