Even though your basement is dry I still suggest the mold resistant (Fiberglass instead of paper) sheet rock available at Home Depot. It meets all code for both regular sheetrock and for green sheetrock used in a shower.
Yes, you should insulate as noise does transfer upward, inside the walls, too.
Also, there are acoustic caulking tubes available and you should use this perhaps at all corners and certainly at base of sheetrock, behind the baseboard.
