Seeing as no-one else has said it. Have you looked at
http://www.pavingexpert.com/

Obviously it focuses on brick & block paving, which may be too much
for your needs, but the pictures in some parts can provide some ideas.

Alternatively, I guess you could pressure wash it, repoint it and
paint it with a suitable hard wearing concrete paint.

Gravel certainly sounds like the easy option but I reckon you'll end
up with those bits in your house instead of the tarmac :0)

Have fun !!
