Hello fellow students and masters of CCNP Voice. I am currently part way  through my CVOICE preparation. I have studied the Sybex and Cisco Press  guides, and am building a CCNP/CCIE Voice lab.
I have attached a pic of the lab which is a work in progress:
==== Routers ====
Voice-
UC520 (4FXS, 4FXO, CME, CUE)
1760
2611XM (w CME)
2610XM
Other-
2610 (x3)
=== Switches ===
3524 PoE
2960
2950 (x3)
=== Firewall ===
ASA5505
=== Phones ===
7970
7961 (x2)
7960 (x2)
7940
Analog (x2)
So I have setup some phones to register with the 2611XM, and some to  register with the UC520 (ephones, ephone-dns) and created voip dial peer  destination patterns to route to each other, but added another layer of  dial-peers by having calls go through the 2610xm (UC520 (CME) -->  2610XM (non CME, but has dial peers) --> 2611XM CME) Then I've  created a vtp domain and joined the PoE switch, 2960, and UC520 to it,  trunking between the three, and set a row of the 3524 PoE ports for the  2611XM CME voice VLAN and a row of ports for the UC520 voice VLAN.
I've been playing around with different configurations. I have a  computer with 16gb of ram that I'm planning on re purposing for a CUCM  server, I probably wont need to do that until after I finish CVOICE. But  I don't know how I'm going to do that or where to get CUCM (?) I'm  hoping the Cisco Press CIPT1 book I ordered will answer some questions  on that.
I have alot of unanswered questions regarding CCNP Voice, I guess thats  what leads me here. I usually work alone on these kind of things but I  think we all need to work together on this one. Theres just not enough  information out there on the latest exams.
