Hi Ted and welcome to the game.
Firstly I hope you continue to enjoy the game and do the credit offers to build up your credits.....but wait until you have built up a good amount to get good clubs that will last.
In the meantime experiment with the different shot types and you will level up quickly (thus better equipment becomes available - buy too soon and you will need to upgrade again quickly) - and ask the forum for advice.
Slower meter can be done by buying slower meter ball and clubs......but whilst it can be difficult at time to hit the ding, the more you are used to the fast meter, the better off you will be when you upgrade as they will be slower. Also balls wear out pretty quickly, so unless you can earn a lot of credits or can afford to spend money......I would wait.
But as I said set you goal as fun........then accrue those credits for a full upgrade.
