1) The starter was working and spinning the engine for about 10-15 cranks (attempts) and now it seems to be spinning freely and no longer turns over the engine. I can hear it spinning but it sounds like it is no longer making contact with the flex plate and the engine is not being turned over.
2) The engine won't fire and the supply of gas to the carb is almost non-existent. The one time the engine turned over for about 3 seconds (after pouring a splash of gas in the carb) the gas flow to the carb increased significantly, but during the cranking sessions when the engine is being turned over only by the starter there is very little fuel flow.
3) I had sparks shoot out of the alternator when the engine briefly turned over. I think they came from where the wire is going to the terminal in the rear of the alternator. Probably a short, making contact with the engine block. I'll look further at that tomm.
The engine is a Ford 302 with a Holley 600 vacuum secondary carb. The distributor is a D.U.I. HEI unit.
What are your thoughts and ideas. Where should I go from here?

First fix your wiring problem. sparks flying out the alternator (or anywhere else) is not a good thing!
Your starter is probably shot. It sounds like the starting gear is not being kicked out on the shaft. Luckily these aren't too expensive - always good to have an extra anyway.
Fuel Flow is easy - get an inline pressure gauge - or a vacuum gauge and a t-fitting. pull the coil wire out so it won't start and crank the car over. You should read around 3-6 pounds of pressure. If not your fuel pump is weak or you have some blockage issues somewhere in the lines. Also it does take a bit for gas to get to the carb when a rig has been sitting a while.
