I am not good at snowboarding, nor do i have gear for my own (apart from a SMITH helmet and goggles i got from a friend) , does anyone have any recommendations for all-mountain boards and/or advice on how to get better at the sport itself (i have trouble keeping balanced when im going fast)

Pay for a private lesson and train in the off season by woking on stuff that improves your balance, core and lower body strength.

skateboarding might actually help in your case

>how to get better at the sport itself
endless vids on YT how to stand and turn, body position (get low and really bend your knees, stay low to the ground). Soft park boards are flexible and easy to turn and play around on. Just buy a used version from a 'play it again' type sports shop. Decent bindings comfy boots that fit. Do not spend a lot on clothes. Be sure to wear a helmet at all times - you can easily bang you head on a rock, rail, box, someone else's board. Buy an inexpensive long board (skate board) and practice riding both ways so when you go just practice riding both ways on beginner runs. Listen to your favorite music, enjoy being outside and have fun. Oh, learn to wax your own board, with the appropriate wax - HUGE difference. I used to think it was waste and the first run of the year with a dirty bottom and when I got off the lift the board litterally stopped dead and stuck to the snow and I fell over. It would barely slide. Snow conditions and board wax/dirt matter. I went straight the shop and got it waxed.
