Shame you're not in the UK ...
With regard to the differences between 2005 and 2008, I wouldn't book a 2008 course. There are huge differences between the two versions (in many ways I prefer the earlier one). Here's a quick guide
. In particular, the method of grouping in tables looks radically different (although underneath it isn't), indicators and gauges are new and charts are rewritten from start to finish. However, there are hundreds of other changes - it really is a completely new version.
Incidentally, for SSRS 2012 the differences are minimal.
