Acoustical treatment for a 16x15x8 room

I've got a recording room with the following dimensions: 16' (deep) x 15' (large) x 7.5' (height) Walls & celing are drywalls, wooden floor and a 5 x 7 carpet in the middle of the room. I use this room for voice-overs, drums, guitars setups. I want to get rid of the small reverb i get in vocals...what should i do? Make the ceiling completely absorbant if so, how and with what materials? Put some panels on each walls? Please HELP! Dan
