They do stack. Based upon my tests (using the comparedps command), maxing Strenghtening is your best choice. Then Final Blow which is only a little better than Auto Attack. Everything else is mostly useless, though I haven't tried a crit heavy build which may take over at high levels.
The thing I found odd was the extra damage of Strengthening far outweighed the slowdown, regardless of how slow it got. That makes me question how stacking really works (or how accurate comparedps is).
I can't really do tests anymore because of the 400 diamond cost. Of course, if the cost was not there, I would engage in exactly the sort of behavior the cost is supposed to prevent...
