Q:
Does the attraction for electrons that nuclei have come from the amount of protons it has in it, or the amount of electrons the atom needs to fill it's shell?

A:

The attraction of the electrons to the nucleus comes directly from the positive charge of the protons, as you suspected. The "shells" don't actually exist as physical objects. They are just descriptions of some of the states that the electrons can be in, given the existence of their attraction to the nucleus.
