Semi-new to F5 - what to read and where to start?

Considering your background, you won't find the basics too challenging.

 

 

It might be worth you following the new certification program as the knowledge requirements of the exams probably fulfill your requirements too. The exam blueprints can be found here: http://www.f5.com/support/training-certification/certification/.

 

 

I'd suggest you get the LTM VE v10.1 90 Day Trial from here: https://www.f5.com/trial/big-ip-ltm-virtual-edition.php

 

 

Well over 20 manuals and guides for BIG-IP, TMOS and LTM can be found here: 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/
