This whole thing only makes sense, if you are seriously interested in B&W photography, I mean "beautiful" B&W, not the pushed to EI 1600, not XP2, not lab developed B&W.
This means, you need to think about the scanner and developing before you go into the camera and lens.
As to camera and lens, the answer is obvious - with an M3, the lens to go for is the DR or Rigid Summicron 50. I suggest to stick to Tri X in D 76 1+1. If you won't like what you see after shooting several rolls, then sell back everything and just stick to what you do now.
