What training?

Hi

I am due to take over the use of Toad (our system is CareFirst) and need to know what kind of training I should be getting, can anyone point me in the right direction?
Is it Oracle or Sql? Or both?
I haven’t used either before (officially) and I have access to some training budget so want to make sure I get the most appropriate course.

Many thanks (sorry if inappropriate forum for this).
