I'm actually using a pieces of a DHTML library called x so it has a cross
browser wrapper. I figured there was a way to do it with the event utility
class. I need the events used with mouse movement too as I've got
coordinate display tied to them.

Since addEventListener isn't available cross-browser, you might want to
try OpenLayers.Event.observe instead.
As in:
function block(evt) {
OpenLayers.Event.stop(evt);
}
OpenLayers.Event.observe(elem, "mousedown", block);
etc.
Note it's probably enough to stop just mousedown, click, and dblclick.
I haven't really followed what you're doing, but you might actually want
to let mouseup and mousemove through. Also, memory management (with
stopObservingElement) is up to you since event listeners on elements
with circular references are trouble for garbage collectors.
