For a chuck recommendation I like the NOVA midi chuck I bought, can use any of the NOVA jaws and is a nice solid accessory.
I agree that buying a set of tools generally means you only use a few out of the set, so depending on what kind of turning you are planning on buy tools as you need them and you will find that you have a much more useful set of tools.
For spindle work I would recommend starting with a 3/4" roughing gouge, 3/8" spindle gouge, and a 1/2" skew. A parting tool is necessary or at least handy in a lot of projects as well.
For bowls all you really need is a bowl gouge, probably 3/8" or 1/2", along with a round nose scraper. Don't try and turn a bowl with a spindle gouge.
I want to die quietly in my sleep like my grandfather, not screaming in terror like the passengers of his car.
