Okay:

Change your map initializer. Instead of using Map("map"), add a
'controls:[]' to your init:

Map("map", {'controls':[]});

Then, before doing the following, do:

var nc = new OpenLayers.Control.Navigation();
nc.activate = function() {
        this.dragPan.activate();
        // This line is removed: this.wheelHandler.activate();
        this.zoomBox.activate();
        return
OpenLayers.Control.prototype.activate.apply(this,arguments);
    };

map.addControl(nc);

This will prevent the wheelHandler from ever getting activated, which
will prevent the wheel from doing anything.
