You could skip all of Batman R.I.P. and not miss much. I personally didn't care for it. It was overly complicated, had more than a few dead-end and dangling plots, and every time he used an iconic character it felt off, strange, or just plain wrong. The end is a total cop-out, too.
However, Morrison's work on Batman and Robin (which I think is up to issue 3 this month) has been pretty stellar. I'm not sure how much you know about the recent goings-on in the bat universe, but this tackles Batman and Robin in the wake of Batman R.I.P. I find Morrison starts to feel more at home in this series. We get some good action, some funny moments, and some real gruesome ones too, as well as some legitimate drama. There is a really twisted new villain introduced, as well.
