You might want to pick up a couple of books, the 'Rampan el Fuego' RF supplement is very good, as is Bob Corderys 'La Ultima Cuzada - A Wargamers Guide to the SCW'.
A few websites (some of these are in Spanish):
http://www.millicheap.freeserve.co.uk/scw.htm
http://www.netcomuk.co.uk/~dpohara/scwcam.html
http://www.users.dircon.co.uk/~warden/scw/scwindex.htm

http://www.fundanin.org/durgan1.htm
http://perso.wanadoo.es/padron/artilleria/arti100.html
Plus there are links to a number of SCW rules & resources off www.freewargames.co.uk
The SCW add-ons in the computer game 'Steel Panthers - World at War' are very well researched as well.
