Mesh grills look good, but I really like the functionality of the foglight. They really do improve lighting a good deal. But of course do what you like best and what you can afford. Put mesh in until you decide to get a new foglight.
As for new Headlights, I wouldn't recommend going cheap. Its your lighting...its the reason you can see at night. Go with something that is tried and true and tested...
