As part of the Ramp Up Guide series I was asked to put together a list of resources to aid the ramp up for our customers. Below is a list of such article headlines as well as some external resources and tools that should be close at hand for any ConfigMgr Admin. I encourage you to delve deeper into the subjects and articles I have listed.
I would also encourage any budding ConfigMgr admin to download the Test Drive Virtual Machine; I learn best by doing, so this would be top of my list of things to look at :)
