First timer help

My friend and I are going but we’re thinking about camping because we heard it’s apart of the whole experience. Problem is we have never camped at a festival before and we don’t really know what we need. I’ve seen some lists and we made our own list but i’m more worried about not being able to put together our setup. Would people be willing to help us? Do we keep our personal items locked up? Do people regularly steal? And is it safe enough for us to sleep comfortably without any creeps? (I did hear everyone there is very helpful and friendly people but you just never know). Also how do the showers work? Oh! And can we wait a little before buying camping passes or do they sell out pretty quickly, we got our tickets tickets but we’re still in the fence. Is it worth it to just get a hotel/motel? (Sorry a lot of questions)
