Where are you located ?

For a detached building you run 2 ground rods

and if you have a concrete foundation with enough rebar in it to qualify as a concrete encased electrode, you MUST bond to that as well.

Sounds like you need a qualified electrician for this job. Just by the questions you are asking I know you are not up for this job by yourself.
Do yourself a favor and hire someone.
