The user guide (Help) is actually quite good, and OCAD9 comes with a free guide book (pdf). Also check the OCAD website
http://www.ocad.com/en/index.htm, the IOF Map Commission site
http://lazarus.elte.hu/mc/ and the Orienteering Australia mapping pages
http://orienteering.asn.au/technical/mapping/.
Surely if you're doing the mapping for your club, they would buy the license?
There's only one place to buy OCAD, so you can't wheel and deal, except its probably best for your club to purchase multiple licenses rather than you purchase one license.
