Good morning everyone. After some time away from these forums I am finally back on track with Cisco

time to head up the CCSP route. I am currently building my home lab and would appreciate some suggestions for CCSP (Also where can I buy good lab books?)
I currently have
- A fully licenced ASA 5505 (Access to cisco.com downloads)
- Cisco 1841 router 12.4T Advanced Enterprise Services IOS
- Cisco 2950 switch
- 2 small servers to host any applications / services for the lab
- GNS3
I plan to continue on to CCIE:Sec
