Jono,
I had stains on my 152 F/9 triplet lens. This was cause I believe from the soft plastic lens cover touching the lens from the previous owner. Anyway, after the cleaning some of my coatings were missing. This was no fault of the cleaning, but I believe the plastic mold release oils or silicon on the cover that touch the lens.
The only issue I had is there is no recoating service at the time. This may because it was a cemented triplet and would be much more difficult. So maybe you need to ask that if the coating becomes damage that you can have the lens recoated and how much just incase. As far as you taking it apart "no". Unless you have the knowlege, optical shop to align, test and adjust, I think it would be just too difficult. When I had mine cleaned it was around $250. But that was a cemented triplet and only had 2 sides, and rather simple.
