I will share what I did on my swap.
I have an M roadster rear subframe on my 96ti. I opted for the stock bushings because I wanted a planted but not an overly harsh ride. The M bushings are pretty stiff already. Urethane subframe bushings will transfer the diff noise more than anything. I did use a urethane diff mount. I do get some of that noise through, but it's not so bad.
I used the ti parking brake cables. The roadster cables were too short.
I am running stock E36 M3 wheels. 8.5 X 17 with 41 offset. Perfect fit. I used the same wheels on the same car before the swap. I did not measure but I also do not recall any difference either. I should have taken pictures "before."

I can't help you with the front. I swapped the S52 with the M3 subframe so I don't know about the M44. My question would be: Why? Swap it when you swap the motor.

Best of luck.
