If you have as much as eight feet to the bottom of the floor joist above, a dropped six inches suspended ceiling is a good alternative to a sheetrock ceiling ... ceiling at 90 inches leaves six inches over standard door and window heights.
An interlocking 'Pergo' floor is a good basement floor, but I reccommend painting (with a latex/enamel) the concrete before applying the sub and finished floor material. Cut four pieces of carpet and place 'fuzzy' side down then place the pooltable feet over each patch.
No, I'm not a professinal carpenter ... and oddly enough, I didn't stay ina Holiday Inn last night ?????
