Try Goof Off , it removes many odd substances and will not harm auto finishes.
No, the color in spray paint is not affected by bleach. A proprietory concrete cleaner or fine sand impregnated with solvent will reduce the appearance of the paint.
It does depend on what kind of paint and how deep it has set in the concrete, but it certainly sounds like a good start to work on.
No, it is not OK. Doing that may inhibit the curing. I always leave concrete for 2 weeks before painting, You should wait to paint until the pH is below 10. Sometimes this can take up to two months. You can get pH strips at any drug store.
It depends on whether it is a water (latex) based paint or a oil based paint. If it is oil based paint it may not come out, but if it is a water (latex) based paint use 'Goof Off' or other latex paint removers with a wire brush. I have used 'Muriatic acid' on some concrete appications.
Yes! The muriatic acid will remove epoxy paint on a concrete floor. Usually the epoxy paint will bubble up and will require a flat-blade or wire brush to full remove and.... repeat as necessary. be sure to nuetralize the floor when finished with (1pound of baking soda to 5 gallons of water). I got this reference from http://foundationarmor.com and it worked!

Iron oxide
Pressure washing is the best option.
DuPont polishing compound..... not rubbing compound.

I would power wash it with a medium jet spray.
Once dried, it usually takes friction to remove the paint. Like a gritty cleanser such as Ajax, Comet, Dutch Girl or a pot cleanser like a brillo pad or soap pad. There are hand cleaners especially made to remove paint usually with a grease compound to get rid of the paint.

ultra fine steel wool for the glass. wax or rubbing compound for the paint ( carefull here test first with compound) I would use 3m finesse.
