Personally, I would not worry about getting on him for a while.
You need to get the biting under control immediately, I would come down on him like a ton of bricks the moment he thought about it or made a motion to bite. Not only is it extremely painful and can cause HUGE amounts of damage(take it from someone that despaired of ever breaking my gelding of biting, I was covered in bruises for a YEAR) but many states call for a hefty fine if your horse bites someone. Being an intact stallion that obviously hasn't had a lot of work done with him you are going to have to start from square one, on the ground, and show him you're the boss PERIOD. Since he is six and barely under saddle I would almost guarantee there are some massive holes in his training, have you ever trained a horse from ground to saddle? Even after he is gelded he is still going to be studdy, has he ever been bred?
Honestly, starting on the ground and giving him firm leadership will go a long way toward improving his confidence. Immediately praise what he does well/correctly and make it hard for him to do the wrong thing. Does he lunge at all? Back, disengage, etc...?
