Coordinate transformations

I am trying to learn about WKT projection information and how projects are actually done in GDAL and PROJ.  Needless to say, I knew very little before this week and I still do not know very much.  First some links:

http://spatial-analyst.net/ILWIS/htm/ilwisapp/find_datum_trans_params_methodpage.htm
http://edndoc.esri.com/arcsde/9.2/concepts/geometry/coordref/coordsys/geographic/transformationmethods.htm

So what is the best resource to learn about various methods?  e.g. Molodensky Badekas Bursa Wolf
