As for #2. there are no hard and fast rules on how or what you use to drive your work piece.
Typically spindle turning is done with spur drives, steb center or crown center drives and stabdard 4 jaw chucks with the proper jaws.
Bowl turning is usually done with face plates and 4 jaw chucks but there are many other methods to drive and support a workpiece.
If there's something in particular you're interested in, just ask. I'm sure someone here can answer your question
Thanks Edward for the info.
