Play around with ESX and explore all of it's features. Experience is a great teacher, the more hands on you get with it the more skilled you'll become
Post on these forums, if you have any questions or need to know more and can't find an answer there are alot of talented knowledgeable people here more then willing to help you.
Finally as far as Novell goes, here's some posts you might read.
