Hesitation at 60 mph and up

1) the car surges when it idles, it sounds like hell. It doesn't die, or feel like its going to die but it runs very very rough. I do not need to press on the accelerator to keep it idling.

Classic lean condition, surging at idle and cruise, put a cupped hand over the carb at idle, does it speed up? Lean. Read your plugs too. Probably need to jet up.
