While other people might dissagree, I see little need for them at low
power levels like your's. Be sure to include a properly set saftey gap,
though. (though even that, if things are working well, and there is no
danger of a strike on the primary side, isn't neccesary).

You may be better off using bypass caps and power resistors is you really
want RF protection. They'll be easier to make/use.

Check the "Almighty Terminal" section of my site: www.electrophile.8m-dot-com
for toroid making info. BTW,  a "toroid" refers to the donut shape, the
sphere is just a sphere, though both are types of terminals. The most
commonly used material seems to be Al dryer ducting. I, and many others,
use it as-is (i.e. no covering with anything else) with superb results.
For spheres, i would suggest brazing, soldering, or epoxying two
stainless steel mixing bowls together, with first having removed the rim.

And one more question, with

Try somewhere between three and six, depending on the size of the caps
being used, and the number of turns in your primary coil
