But as you said, I'll need something around 1/100 anyway to stop motion.


Now since it's a DSLR, I can go to let's say 800 ISO to compensate the a-bit-slow f/4 and lack of IS and still get much better results than with my P&S at f/2.8, 50 ISO - correct me if I'm wrong as this is also one of the reasons for moving to a DSLR... with my P&S there is never enough light indoor (I prefer no flash at all) and I can't even think about going to ISO higher than 50.
