For Dick, I would go for Batman: Dark Victory and Robin: Year One (the latter's got some incongruities with the former, but mostly concerning Two-Face), and then Nightwing: Year One. You could read Batman: Year One and Batman: The Long Halloween too, or watch the animated movie of the former. Long Halloween is a prequel to Dark Victory, and though it doesn't have Dick, you need it for Dark Victory.

For Jason, Batman: A Death in the Family and Batman: Under the Hood. You could also read Red Hood: The Lost Days.

I would also suggest Batman: A Lonely Place of Dying, which details the origin of the third Robin, Tim Drake.
