I just took the IPK Advanced, IPKII basic and advanced, SV8100basic and SV8300 basic all online.
I think a classroom would make actually passing the exam easier, but it wasn't that bad. There is a IP prerequisite that needs to be passed in order to take the SV classes.
If you are an end user you can sign up for training at the NEC Unified website, but will not be able to call the tech support line unless you are a registered dealer.
Going on what the others have posted, I also would reccomend finding another dealer. These guys deal with this stuff everyday and you have to figure in what your time is worth.
