Agree with everything you said
I just hope MSD doesn't experiment too much with the lineup until we have secured a place in the QF. Cricket can be a harsh mistress, we ought to respect it.
I guess his changes might be minimal, mostly on the bowler's side. Our batting need not be changed and I would dare say - should not be changed much. Because as batsmen, getting that rhythm going is very important. For e.g., I wouldn't want Dhawan to miss a game from here because he is hit that sweet spot with his batting and there will be the fear that a break might disrupt that rhythm. With the bowlers, there is also the issue of over workload and so rotation would be needed there to avoid burnouts.
