Will I have to amend my tax return my husbands employer sent us a FICA claim certification after I filed with a refund of 87.00 and new corrected W 2s.

generally, no because if the only changes were boxes 3 thru 6 on the W-2 these will have no effect on your income tax liability.  A refund of overwithheld FICA taxes must come either from the employer or filing form 843 directly with the iRS
