I would highly recommend John Couture's book on Tesla coil construction. 
It is very straight forward, rather inexpensive, and has a lot of relavent
charts and information to guide you.  John is a regular reader on this
Tesla List and could respond directly to you.

A variac is essentially an adjustable transformer (auto-transformer) that
is commonly used by Tesla coil builders in front of the neon sign
transformer to bring up the voltage slowly.  The variac is also a good tool
to use until you get the primary tuning clip in the proper position for
best resonance -- it helps save your transformer and caps from excessive
resonant rise until the energy is being coupled into the secondary coil
where it is desireable.

Hope this helps out.
