Sitting motor

I have a 318/340 that hasen't ran in about 4 years. I wanted to prime the oil pump before I turned the motor.So I didnt line up TDC and pulled the distributor and gear.After I prime the pump is there any other pre start up I should do and when I reinstall the gear does it matter how the gear goes back .The distributor is the original one.What distributor should I go with.Thanks
