I don't know about installation but it's probably not worth the effort of upgrading if you already have the M3 bushings, I doubt they have significant flex in them when installed.
I'd go straight to poly if coming from the stock bushings, but from M3 bushings I doubt I'd bother upgrading.
For the runflats I guess it depends on the wheels, hard to say, but I don't think you can even push your car hard enough to benefit from your suspension upgrades with the stock runflats. They lack that feel that lets you judge the grip limit, and they just don't have as much grip either in my experience.
Dumping the runflats is the best handling upgrade you can do IMO. My car, after M3 arms, poly SF bushings and diff brace, is far more comfortable than it was before the upgrades on the 19 inch runflats.
