In Hep. B Vaccination, we are given the surface antigen and we make surface antibody which is protective (Active Immunity).
-Since the sAB is an IgG does this Ab cross the placenta from a mother who was immunized years before her pregnancy?

I think it crosses placenta but the protection is passive and will wane with time so they should still get vaccinated to achieve active response.

So is the newborn protected from Hepatitis B if he is infected?

A new born born to an Hep B immunised mother is protected for 3 months passively. but we recommend giving hep vaccine from birth to develop active immunity.
