Drake,
     As far as using thinner wire is concerned, it will decrease the
overall output of the system (however it seems, at least to me, using thin
wire, makes quenching much easier).  For the spark gap, what are you
using?  For my spark gap, I used "L" brackets, the wire attached via a
ring terminal either around the bolt holding the bracket to the base, or
the bolt in the gap (if you are using the Richard Quick, I'm sure there
are bolts holding the coper segments in place, that one could attach a
ring terminal to).  If you are using an MMC, if it were me, I'd wind the
leads around a brass bolt and use a ring terminal.  For primary tap, I use
one of those Bracket things shaped lik this 
_ _
 U
made of copper and bend it backwards around your primary coil so that it 
acts like a clamp.  Thread a bolt and attach with a ring terminal.  I hope 
this helps.
