And above all, don't stress too much about the written. For most people who are properly studied for their CCNPs and have a few years of solid Cisco experience, this exam is very trivial and is just a ticket to the lab. If you look at my thread I started a few months ago I read only Routing TCP/IP Vol1/2 and the doccd and I passed okay. It's more of the edge topics like VSS, EIGRP OTP, PfR, 802.1x which in retrospect I should have studied for more. EDIT. I skimmed the OCG for the v5 written, it won't cover the topics in any where the amount of detail you will need to know for the exam.
