I'm using SQL Server 2012 Integration Services Design Patterns by Andy Leonard, Matt Masson et al. I've found it very useful. I'm also using Professional Microsoft SQL Server 2012 Integration Services by Brian Knight, Erik Veerman et al. It has also been very useful although I haven't spent as much time with that one except to look at new features. Not using SSAS at this time so I can't help you there.
