You will have a pretty good idea of city & interurban traction with the above three books. Note that electrical wiring for traction in these books refers to DC -- If DCC is preferred, substitute modern DCC wiring like you would for any other 2-rail model railroading layout.
When the "Model Train Magazine Index" is back online (first quarter of 2011) you can get more MRR articles. In the past, I have purchased many of these out-of-print article resources on eBay.
If you model live overhead (instead of running 2-rail pretend-overhead) -- You will be soldering & scratchbuilding and creating good brass line pole wood-templates for consistency. The operative process is take your good 'ole time in planning for traction.

You might already be aware of this, but in an issue a few months back Model Railroader did an article on a layout titled "Connecticut Streetcars" or something to that effect. Seems like that would be along the lines of what you're seeking.
Model railroaders who model trolley lines are as rare a bird as trolley lines are in reality. Some time ago, I did a search on this topic myself and the result was, to say the best, meager.
