Hi martin and if no one has already done so let me welcome you to the SpanishDict forum

The number of the possessive adjective has to match the number (singular/plural) of the object that it modifies and not the subject (i.e. does not matter if the verb is singular or plural).

mi libro/mis libros - my book/my books

mi zapato/mis zapatos - my shoe/my shoes

This reference article on possessive adjectives may help.

Answer 3

Yes, you are matching the possesive "mis" to the word it is describing, "libros", which is plural. If you had only one book, then it would be "mi libro".
