I have read on another post that 75par30 soft Par lamps are better suited for general lighting. Would these be better for the six surrounding lights, and MR16's for the pool table lights?

Using frosted par 30 lamps is an excellent way to receive maximum light with little or no glare. Use them recessed inside a good baffle or cone trim. Your lighting plan sounds fine and the use of recessed or a billiard light will both work. If you use mr16's over the table, be sure they are floods and not spots. A billiard light will add a decorative elemant to the room. If you use the recessed lights down both sides of the room, you can use a sold shade on your billiard light.
