If you need more examples to supplement the ones you've currently tried, 
then Charles Walker's "Capacitance, Inductance and Crosstalk Analysis" 
book (ISBN 0-89006-392-3) provides analytic solutions to several 
geometric configurations. Also, I found Charles Butler's two papers 
"Capacitance of a finite-length conducting cylindrical tube" and "A 
Useful Transformation of the Free-Space Green's Functions with 
Applications to Analysis of Wire Structures" to be useful too. Richard 
Becker in "Electromagnetic Fields and Interactions" (ISBN 0-486-64290-9) 
provides an analytical solution to the infinite parallel wires in free 
space problem.
