it depends. if you've decided to use a specific style for your camp, then you could buy just the equipment for the areas that use that style. if you are still using a mix of styles in your camp, just level everything out first.
Hey man, Check out the forums when you get a chance...Theres a link in the top left corner. As for your question about buying better equipment, All it means is your fighters will train quicker as in they will get there stars faster than they would with lesser equipment. The better the equipment the faster you'll get to 4-5 stars. Hope this helps.
