Just as an FYI - there are multiple forms of "currency" in the game, and each do different things:
Silver shield "Tokens" - used to level up in the Pro Pass...after you earn a certain amount, the next level in the Pass is unlocked. You have to manually go into the Pass to claim that level's reward. There's a free reward, and a Premium one that requires you to pay actual money to unlock.
Gold coin "Reward Points" - spend on gear/clothes and on daily tournament entry fees
Red triangle "Tickets" - used to enter tournaments only
Yellow hexagon "Skill Points" - used to level up the attributes of your golfer
Green diamond "Points" - these are only obtained by spending real money on them...some items in the Store are available to be purchased only with this currency.
So like bigkev said, you can level up in the Pro Pass, earn those rewards, and then spend the coin "reward points" on gear and such in the Store tab and not mess with your attributes. Only the "Skill Points" will affect your golfer's abilities, and those are used under the "Golfer" tab.
Here's a video on the currencies:
