I now have my CCNA Service Provider certification!
I received Global Knowledge training (with their two books and Lab Manual) for the SPNGN2 (took this exam first):
640-878 SPNGN2
Building Cisco Service Provider Next-Generation Networks, Part 2
I self studied for the SPNGN1:
640-875 SPNGN1
Building Cisco Service Provider Next-Generation Networks, Part 1
Much of the content for both of these exams can be found within the regular CCNA. I would say that 60 to 70% is already covered within the CCNA, maybe going a little bit more in-depth in some CCNA subjects and less in others. IOS XR Fundamentals is required reading for both exams:
Cisco IOS XR Fundamentals: Mobeen Tahir, Mark Ghattas, Dawit Birhanu, Syed Natif Nawaz: 9781587052712: Amazon.com: Books
