Pertronix have a drop in replacement for the points in your stock distributor that effectively give you electronic ignition, easy to install and works well, no more messing with the points trying to get the gap and dwell right.

Since I had read about it before buying my '67, the first thing I did was install the Pertronix ignition. It's only a 10 minute job and the directions were pretty clear. It's a good idea to change the coil while you're at it. Pertronix also makes an upgraded coil.
For rewiring, you can pick up an electrical diagram pretty cheap. That's a good start. Look in any of the big parts catalogs like NPD.
