You don't normally need to prime a wall that is already painted.

Not normally, but in a case such as this -- where he's painting over a color
that will be difficult to hide -- a tinted stain-blocking primer can be a
great help.

Priming is not for color - it is for adhesion and sealing in stains.
Buy cheap paint and you will likely need more coats than if you used a
quality paint, like Ben Moore.

Absolutely right. Cheap paint is usually more expensive in the long run.

Two coats of paint is normal.

Right again.

Dark color with light over it may need a third coat.

Or two coats over a tinted primer -- which may well be less expensive. Depends
partly on the size of the room: for example, if one can of paint is not enough
for two coats, but two cans is enough for three, then skip the primer.

You do need to be sure
the wall is clean and free of dust. Any good household cleaner, rinse
and dry.

Amen! Too many people omit this step... then post here wondering why the paint
is peeling. :-)
