Definitely the sensible move if time is more important than money. I think you will be impressed by how nicely the tool is made .. when you get it you realise why it costs so much more than the plastic "pastry cutter" the PD-M520 et al use. Shimano show no sign of replacing the PD-M324 so I suspect over time this will be a cheap purchase (I have FIVE pairs of PD-M324 so the tool is about £8/pedal)
Regarding the outer nut you are already aware you may need to file off the sharp edges of the hex. Some people have not had to do this (I did) so I can only think there are different pedal axle nuts used at different times... as you say .. mad.
The final pain with these pedals (!!!) is placing the deeply hidden inboard bearings. I struggled with this (and I think others have as well) so I have knocked up a quick diagram of the method that works for me. (Note I do the inboard bearings first - the outboard bearings are much easier and can be done last) This method gives you a really good view of the placement without anything getting in the way. It still takes lots of painstaking placement to get all the balls in but its a reliable repeatable process which avoids "backward steps" with dropped balls etc. I am old and short sighted so take my glasses off to do this (good close range vision) but YMMV regarding eyesight. See if the diagram makes sense ? Its only a suggestion .. I am sure there are lots of other ways of doing this .. for me this was the route back to sanity though.
