As Icon said, are you having trouble hitting the ding? The club speed of the clubs you have is fairly fast, especially compared to the starter clubs. Also the starter ball not only is fast, but you will have little control with it. You could try to use a slower meter ball to see if that helps - even the slower meter WGT balls available in the pro shop are much beter than the ball you are using. You may want to consider getting a couple of good wedges as well, these can save you a lot of shots.
As for the tutorials I can't give an answer but look at the section - optimizing your PC.
It does take a while to get used to new clubs with a faster speed, and takes a lot of practice and persistence but worth it in the end.
