Battle/Contest Team Make-Over!! (Platinum)

[G e e ksteria]

Okay! Listen up! This is the team that I have worked, very, very hard to achieve (considering that most of these evolve by happiness). However, I need to be able to win contests and the Pokemon League at the same time. So please, I need some advice. Change movesets, change items, but I can't change the Pokemon because it took me a really long time to get a hold of these. I know nothing of EVs, stat altering, so I fashioned these pokemon based on internet research. So please help me! rating, and critising would also help and is very much welcomed. Thank you!
