1) Can Doc Scratch know your characters past?: Yep!
2) How much can he know?: Anything's cool with me!
3) Do you want him to know your character's stay at Mayfield? Sure!
4) Will your character be aware if he his gaining information about them? Nope. Zidane does seem to have some telepathic awareness but it only seems to work with other Genomes and maybe Garland (canon isn't clear on this).
For both Zidane and Apple Bloom!
