The quick answer is that it is possible for the couple you describe to have kids with blue or green eyes. (Although less likely, it is even possible to have a brown-eyed child.)
In terms of hair type, by the traditional sorts of theories that are out there, it isn't possible for a curly headed and a straight haired couple to have straight haired kids (or, by a strict definition, curly haired kids either!). Of course, genetics is always more complex than the traditional sorts of theories.
