Run from such a trainer. 3 years old and fine to jump! Heck, I just started jumping (little higher then yours) this month when one of my mares turned 6, other one coming 6 in Sept. While I don't think such little jumps (like one in video) to have a big impact, please, don't go to anything higher then that for at least another year or 2.
As for rearing and bucking, considering it's not a health issue (like back or tack) go for the -good- trainer who knows how to deal with horses like that.
BTW, martingale will NOT solve the behavioral problems like that, in opposite can make things even worse.
