Jayendra, if you are a member I'd recommend you join the Linkedin 'F5 Certified Professionals' group. There's a fair bit of very useful information that can be found there, including some from Ken Salchow; the guy who runs the technical certification program.
You can read through the manuals here (you can browse to any version you want): http://support.f5.com/kb/en-us/products/big-ip_ltm/versions.11_2_0.html
Free, self-paced web-based training related to basic technologies and concepts, changes in new software versions and basic LTM configuration are available via the F5 University available here: https://university.f5.com/.
You can also download a reading list from the TCP website once you've signed up here: http://certification.f5.com/.
