MGD.....

You'll find some good info at the Musicians and Instrument Makers Forum: http://www.mimf.com/cgi-bin/WebX

The adjustments you talked about are fairly simple and can be done at home (with care - especially if cranking the neck). On the other hand, they can be done quite inexpensively by a good music store (with technician) or a luthier, if you have access to one. That would give you a good chance to discuss your instrument, and its strong and weak points.

Obviously, this recommendation is much stronger if we're talking about a fine instrument.
