Use the JHCTES program for answers to your questions. The program gives you
an estimated relative output via spark length. For example if the secondary
inductance is increased the spark length will increase provided other
variables do not change. The basic equation shown in the Tesla Coil
Construction guide is

      Vs = Ls di/dt

   Vs = secondary voltage
   Ls = secondary inductance
   di/dt = time factor

With this program you can explore dozens of combinations.

Would it be better to make a 6" by 30" secondary with 1200 turns of 22gauge
wire or a 6" by 24" secondary with 1200 turns of 24gauge. I'm leaning
the 24gauge, since the cost for a 10pound spool is the same but I'd have
more feet left over with the 24gauge. I'm also sick of NST's dying, whats
best way of going about getting a potential transformer?
