Hi,
That is correct, it looks like if you already have the MCITP: Enterprise
Support (Vista), then you only need to take 70-682.
I haven't taken an upgrade exam yet, but I'd imagine that the way that I
would prepare for it would be to study the material for the two exams
that make up the MCITP: Enterprise Desktop Support Technician 7:

http://www.microsoft.com/learning/en/us/exam.aspx?ID=70-685&locale=en-us#tab2
It looks like both of these have self paced training kits with them to
help you study the objectives. My guess is that if you have the
knowledge for both of the exams, then you should be able to pass the
upgrade exam (at the cost of 1400 pages of reading or so, possibly
skimming familiar material).
