i guess i disagree on the time schedule for the bodywork. for the rust i'd suggest doing is little work as possible now, but with the maximum benefit. in other words, don't spend tons of time and effort on a+ body work if you wont paint the car for two more years. just do enough so thar your investment is protected.
in that time. your skills will improve and you'll probably be able to do any body work better and faster than you could now. also, you'll come to think of rust work as a pain in the ass that takes time far too much time away from other more significant mechanical things. also, you may even acquire many of those panels and parts in far better shape from the contacts you'll make while the project is under way.
if the car is going to remain in a cool and dry garage, the rust will proceed much slower than it would if out in the elements. i might even argue that in that environment, you probably don't even need to do anything to it.
however, you can learn a good bit and get some idea of what you have to look forward to by taking care of the bubbling and any "crunchy" areas. a course grit disc on an angle grinder should expose the metal jsut fine. take out the most heavily rusted areas and see what will need to be replaced. if you're going to wait a while, jsut paint the touble spots with whatever paint you have handy. (most primers will allow oxygen to reach the metal and rusting will start or continue if you dont seal with a paint topcaoat. )
if the car is going to be in the elements at all, then the rust is more of an issue. the already rusted areas will trap moisture from rain, condensation, humidity, etc. and the rusting can increase exponentially. in two years significant corrosion can occur on unprotected metal if left outside.
unless you have access to industrial sandblasting equipment and facilities, don't plan on it for anything more involved then trouble spots or small parts. it creates an insane amount of mess and takes a good bit of time. with all that involved, you're probably better off sending the stuff out to be handled by someone with the ideal set-up.
btw, where are you? im in central pa and probably have a lot of the body stuff you may need.
