I had a look into your signature ....
CCNA:S(completed) Security+ LPIC-1 CCDA (maybe) MCSA:S
Looks like you are looking for quite a diversified field having hands into Linux , Windows , Cisco . Being a CCSP I would advise you to go for it definitely if you work for Cisco Partner or for an enterprise having installed Cisco as their networking appliances . There are lot of people in their early career looking for CCSP because the word S says Security which offcourse looks attractive . You should be careful because when you come to configuring routers , switches , firewalls etc you must be good at routing which could be achieved by doing CCNP rather than CCSP .
For example:
-- DMVPN : When you configure DMVPN it is definitely a type of VPN however it involves a heavy amount of routing .
etc.
As for me I work for a Cisco Partner so here we have to be strong at the basics which are off course routing and switching to handle clients in emergency cases and then look into VoIP or Sec. or Wireless fields respectively . Thats the main reason I dont have my CCNP .
As far the materials are concerned I would highly recommend Internetwork Expert newly launched CCSP Class on Demand ( offline ) . Never go for CBT Nuggets when it comes to Cisco
