Plunk down the money for the one piece suit - I lived in mine and loved it You can now ditch the fleece pants (heavy and bulky), especially if you're bringing another pair of insulated ones - your boots come nearly up to your knees anyways. Consider leaving the belay jacket also. When you're moving it will be too warm, especially with a big pack on, and you already have the softshell and gtex. When you're stopped, just throw the big parka on (Nautica...?).
