You are aware that the software versions you have listed their aren't compatible (MW 1.19 and later needs at least MySQL 5.02 according to min requirements).

Additionally, I don't know which guides you were looking at, but all the relavent guides I am aware of are perfectly accurate for 1.20. Furthermore, user groups haven't changed since MediaWiki 1.5 (Well the ui changed a bit more recently, but we're still talking years ago), so you'd be hard pressed to find a guide so old that it was outdated.
