As others have said you can only have 14 clubs and you can use any make of ball. One extra piece of advice I would give is to get yourself a marker pen like a sharpie (other brands are available) and put some kind of mark on your ball before you start playing with it, just something simple like a couple of dots will do. Chances are that someone else will be playing with the same make and number of ball as you and this will help you to identify it should the need arise.
Best of luck tomorrow.
