Assuming the car is driven the day or two before the hard starting, If the fuel is reaching the carb and not all dropping on the ground doubtful the fuel pump is the main starting issue. It could also be the choke is not closing properly or the carb is in need of a rebuild.

On the pump replacement, I would get an already rebuilt exchange pump from Kanter or Max or else send your pump to one of the rebuilders and have it done. If your mechanic is willing you can also get a rebuild kit and he could do it.

Electric pumps are usually added more for convenience than actual running operation. Many have cut the line and added one near the fuel tank to have it push fuel thru the mechanical pump. That way it can be switched on and off with a hidden switch and used only when needed. If you wanted to do that be sure to get the type that allows fuel to be drawn thru when the electric pump is off. Airtex has a couple of 6v models many on the forum have used.

Benefits of adding a second pump are the electric can be turned on for a brief period to prime the fuel system after fuel evaporates due to an extended period of inactivity. This saves wear and tear on the starter since the engine doesn't need to turn over as long to bring fuel into the carb. Another advantage is because of the higher volatility of todays fuel sometimes vapor lock seems to be an issue. The electric pump can pressure the system before the mechanical pump and many times alleviate the symptoms.
