You will file as a non-resident alien for 2008.

You become liable for Social Security and Medicare taxes thed day your H-1B visa becomes effective.

You SHOULD be able to claim the standard deduction under the U.S.-India Tax Treaty.

The website below has a tax calculator:

Perdiem CAN be taxable. It depends on how the per diem is paid and accounted for on the employer's books.
