Hi and welcome to the game. As already stated regarding tiers/levels I have nothing to add. But if I were you, just play using the starters equipment until at least mid level 30s. Anything you buy now will not last long as you move through the tiers. So a driver than can drive 240-250 will be fine for a while but you would need to upgrade again when you become Master tier. I always recommend you start with a couple of good wedges - from your tees this is where you can reap more rewards than a driver.
As said, try earning credits and accumulate them until you can get decent gear that will last, and try and learn as much as you can in the interim. There are great tips in the forums,just search or ask if you are unsure on any aspect.
