No question, if one wants to do a system overhaul prior to retrofit, what
you outline is a good idea.  However, if the system has no leak, or no known
leaks - in this case system bled down after sitting for 6 years, one does
not always need to tear things apart.

Didn't want to get into a debate about how best to recharge a system.
Similar issues are posed when one tries to determine to what extent to
rebuild an engine.

$100 including the R134a. You can do it "cheap" for under $30. Doing it
"right" means replacing: service fittings, dryer, all o-rings/seals, and the
expansion valve (or oriface tube if so equiped). Then flush everything (have
to remove the compressor to flush it). Now evacuate for a minimum of 2 hours
and make sure it will hold a vacuum, now refill with ESTER oil and fresh
R134a (ester is R12 & 134a compatible and it is a good conditioner of seals
and o-rings) and finally adjust the AC temp sensor to whatever temp you
