if i specified a controller with one timing parameter set, such as DDR2-800MHz.
Should it support DDR2-667MHz at the same time?

The different speed grades have different latencies, and should generally not be mixed. Its quite possible that the timing parameters for a 667MHz RAM can be used with the faster 800MHz part, but not the other way around. Unless of course, the actual speed of the controller is slower than the rated speed of the DDR.

Would it support samsung's and kingston's memory plugged through the same slot.

If the memory is the same speed grade, then the timing parameters should be vendor independent.
