There is a help thread for questions exactly like this...
I am not sure about the 2008 R2 server but probably.
As far as which SQL you need to use that depends on which server files you are using. It could be either 2008 (early E6 releases), 2012 (E5.2, 6, 7.4, 8.1, 9.1), or 2014 (ismokedrows re-released E9.1 clean telecaster)
You pretty much need to follow the guide for which ever epic you are using. The guide will explain everything you need including which SQL to restore the back up files on to.
