So, I took the TSHOOT today, and passed, with 931/1000. I knew all along this would be my exam, I'm a troubleshooter by nature

Given I'd already passed the BSCI and BCMSN, that means I'm done with the CCNP!
In terms of materials I used for the exam? Nothing but the topology and BSCI and BCMSN knowledge. I built the topology (I have a blog post about it for those interested), checked the exam topics, and went over my notes for the BSCI and BCMSN to make sure.
To the people who passed the BSCI and BCMSN with relative ease, or at least those who have come away knowing every last bit of detail (if you know your Inter-area LSAs from your IGMP messages), then I wouldn't bother with the official cert guide if your aim is to pass the exam.
