Hi,
Even after 4-5 years of using various Linux distros (which I also recommend) like Red Hat (now Fedora) Suse/OpenSuse, Ubuntu, I still consider myself a newbie, after I've seen what's being discussed on this list. That, and also because I'm a sysadmin for a company using 101% Microsoft products, I have fun with Linux at home.
Here's what I recommend:
Find yourself some book or if you don't have the time, tutorials on the internet are much shorter to follow (don't just stop at one, 2 experts will have 2 different opinions).
Then, after you've been playing with terminal commands, you could give yourself small projects/homework like: learn scriping (bash, perl, python or whatever) and do some automation with it -- automatic backup for some files in your home dir or something similar. Also, what can/should try is, if you happen to have another device at home that's able to run Linux and can stay on for a very long time, build yourself a dns+dhcp server.
Good luck, and welcome!
