You will find a lot of that here: http://helpx.adobe.com/pdf/premiere-elements_reference.pdf
Also, the Help File, F1, will have good material too, and is active on-line, so there are some comments via Community Help there, as well.
If you are new to PrE, here is a partial list of useful resources: http://forums.adobe.com/message/3953827#3953827
I particularly recommend Steve Grisetti's Basic Training Series on Muvipix.com.
Excellent, and glad to have helped.
You already have a head start with the Classroom in a Book (I have not used the PrE version, but have many, many others, and really like them).
Steve's Basic Training is a great place to start, as one will by-pass many common problems, just following his tutorials. Then, he has a more extensive Learning Series on Muvipix, plus a Tips & Tricks section (and book). He has also been working with Lynda.com, so some of the tutorials from them, are probably from Steve.
I also am a big fan of Steve's books, find them well-written, and very useful. I am more of a "book guy," than a tutorial person, or even an on-line Help user - guess that is just what I grew up with.
Good luck, and happy editing,
