The door is in good condition, was new a few years back and so has only
had one coat of gloss on top of the undercoat. A few small cracks have
appeared. Want to paint it again.

Do I need to undercoat it? If so is it ok to undercoat with a white
undercoat and then paint it with black gloss? Or can I directly apply
another coat of gloss seing as its in good condition

Any recommendations of paint would be appreciated?

Consider using a flexible exterior gloss. It will last longer than
ordinary gloss.
