Basketball tips please?

I just started basketball a couple of days ago and this is my first year of being on the bball team and im not bad but im not the best and i want to try my hardest and i want to get better at it so i would like some tips on how to shoot a free-throw shot, like a certain way that works well? and then left side lay-ups, and overall good advice i should know about bball. Our coachs arent the best at explaining things so it would be nice to know how to do something properly. thank you! :)
