Learning SSIS 2008. Recommended books?

Hello,

For my new position working with datawarehouse, i need to learn SSIS. Does anybody know any good books to start learning. Or online training? Or digital media?

The faster i could start my learning the better, so anything that doesnt need the postal service is the best. But i also want a book for later reference, so suggestions on that too would be good.

Ive worked with SQL Server 7 and 2005 and are familiar with the basics and good understanding of SQL, but never done anything with SSIS before.

Thanks in advance!
