Subject: modern Z80 operating systems (beyond CP/M)

From an accumulation of postings and a recent subscription to the Computer
Journal I am slowly learning that it is to my advantage to get one of the
replacements/overlays for CP/M and run it on my dear old Trash 80 Model II.

I have accumulated an assortment of names such as TurboDos, ZDOS, ZCPR3,...

Can any of the enlightened explain what all these are?  For instance: 

    Do they replace the CP/M CCP?  Are they total CP/M replacement or what?
    What do I need to get such animals running on my little grey box?
    Why would I want to get one or more of these?
    What is the history behind these packages?
    Any reading material you can recommend on the subject?
    Any thing else that is relevant?

These things are very inexpensive - as is almost anything CP/M so I am inclined
to spend a little money and experiment.
