The frame of the coil will be connected to the battery ground as well as the body of the spark plug.
Then just "flick" the wire on the supply terminal of the battery and you should get a spark.
Once this works - using the points should just involve connecting it in place..
Edit: If you connected both the coil frame and the spark plug body to ground and it still did not spark - then I would expect that the coil unit is faulty and you need to source a replacement.
Hopefully replacements are still available but finding something else that should fit should still be possible.
Edit 2: Back in the day we used to use simple timing lights - just a strobe light that was triggered by the spark and ran off the battery - this enabled one to see when the spark was occurring. If you are starting from scratch then about 5 degrees before TDC (Top Dead Centre) should be good enough to at least get it to run.
