You can file joint return as residents for 2008. You must wait to file till you complete SPT in 2009. You will attach W7 (ITIN application) with your tax return.
Read Your U.S. Tax Return: Substantial Presence Test

It will be late May 2009 before you can file, so you need to submit Form 4868 to request an extension to 15 October 2009 to file. If you OWE taxes (not likely), include a check for what you owe with the Form 4868.

It IS worth the wait to file jointly with your wife and cliam your child as a dependent, even if you must claim ALL world-wide income from 2008 on your U.S. tax return. You will be able to claim the $1,000 Child Tax Credit for your daughter, and file Form 1116 to claim credit for taxes paid on your income from your home country.
