Welcome to the forums Wolf.
First a link

This Country Club is one I can highly recommend having just sponsored a open community tournament - speak to them with regards to membership. A good CC will make your playing at WGT much more rewarding.
You seem to play on mobile, so I am no expert at coins and credits but generally players in the US can play this game with upgrades without spending. Patience is the key. Alternatively, IMHO, this game is pretty cheap entertainment, so is worth opening your wallet if you can afford to.
Read the forums as there is some great advice to improve your game and do not be afraid to play with higher tiers - most players are willing to give tips.
Most of all, enjoy the journey - albeit a frustrating one at times, but you will get out of it what you put in.
