hi Rhem,
it seems you have a lot to ask about the usage of "got"(?).
anyway, I don't know how the word "got" confuses you but, take a look of these examples:
Do you have a car?
Have you got a car?
He hasn't got any friends.
He doesn't have any friends.
She has a beautiful new home.
She's got a beautiful new home.
While both forms are correct (and accepted in both British and American English), have got (have you got, he hasn't got, etc.) is generally the preferred form in British English while most speakers of American English employ the have (do you have, he doesn't have etc.)
The past participle of the verb get is gotten in American English. Example He's gotten much better at playing tennis. British English - He's got much better at playing tennis.
I hope this clears you up.
:)
