This might be a harder transition on you lol, I did hunters for years, then switched to jumpers, with a green horse, so getting my brain out of hunter land was a bit difficult. Grids like said above are very helpful, when you start going to shows almost ride it like an eq course, make the turns tighter but make it pleasant for you and your horse. Once you and your horse are more comfortable with jumper courses the speed will come. Work on adjusting your horses stride, take a stride out and then add one, so that while you are on course he is adjustable. Jumper courses have options some times, like an easy five or a moving four, so its nice to have the adjustability. As for equipment its pretty lienient, most bits are allowed, as is most tack, standing martingales aren't allowed past a certain height, I believe it's 3'6. Good luck!
