What I did was I first replaced the battery since berries are a necessity. Fixing the battery will also give you the chance to meet the pokeblock master and make gold blocks with him. Now all you need to worry about is your move set for the contests and which pokes are in the contest with you. Good luck anon!
Oh, and if you have Colosseum/XD, some berries will make your chances of winning easier.
