Chainline can be a ***** for the uninitiated, but in the end you'll have learned a lot, and you'll see its not that big a deal.
Yes you can adjust chain ring distance from the spider with washers, but that's kind of a gross looking way of doing it; it's much nicer to finesse the bb spindle length.
FWIW, lots of other conversion riders (incl. me) get a nice circa 42mm chainline (this lines up with standard track hubs) with a set of 80s 600 cranks (50-70 bones on ebay/ craigslist, and way nicer than the cranks you are asking about) on the outer ring position, and a 107mm shimano square taper cartridge bb.
Also, the ssfg forum is a good place to ask about this stuff.
