Michael Jang's books albeit hard to understand and read at times... are great for prepping for the RHCSA. I have my RHCSA, haven't started on my RHCE yet.

My friend says this one helped him out a lot.
As for the command line, there's a ton of online crash coarse resources you can find with a Google search. Also, there's the lower 100 courses Red Hat has and I'm pretty sure they deal with command line if you have the bucks, or company funding for it.
If you haven't already, get a Red Hat Admin book (similar to this) and work through it. It won't teach you everything, but it will teach you the basics.
Even more curious, that the book has been updated recently.
