Sorry so slow in replying Inq. I have been swamped with work as of late.
As far as some good sites for Tesla building here are a few that i found and referenced quite often.

Information sources about how to build your own Tesla Coil (this one has many other links to scematics and other sites with info.)

Altair - Nikola Tesla and How to Make a Tesla Coil (well documented specific projects)

Trashy Tesla Coil a tesla coil made entirely from junk from dumpster diving (this one is for coilers on a budget)

Great resource of information here. Nikola Tesla Page, Tesla Coil (Bill Beaty's Homepage)

Generally my suggestion is to investigate based upon the foundation of the coil, that being the power supply. Dependant on your volts is your capacitance. I have read that you ideally should have 2X as many caps as you have volts provided by your transformer. If using a static spark gap tuning your coil will involve knowing more about the frequency of your TC's secondary coil. However, by hooking up a rotary spark gap you can force the resonance that you want, but be warned that you should be cautious and not over drive your capacitors in this manner. You can tell when running the gap how hard your pushing your caps by the intensity of the snap. Once again these are only my learned and interpreted suggestions.

More info here soon.
Thanks
