MCTS or MCAD or MCPD or MCSD

I was planning to complete just one of the core exams for MCSD:[b]70-315[/b]. MS seems to have two new certifications path for .Net 2.0 and VS 2005 professionals – MCTS and MCAD.

Now I am little confused. Any recommendations on which path/exam is better?

Recommendations for good books/exam preparation material is appreciated :d
