Fantastic Lynn! Soon you will be wanting the 2x teleconverter too!
Try using it in manual mode, that's the only way you will get the full magnification and really it's dead easy! Set the lens to 'M' on the side, you also have a distance setting which I rarely take off the 0.5 metre range and if I do I forget to put it back.
Also set the camera to 'M' then all you need to do is experiment with speed (I use mostly 1/160), EV, and f#. All changeable according to conditions, you will learn I'm sure and if you ever need help give me a shout.
You will also need to set the ISO, I leave it on 200, I use the back fill-in flash setting (I think) and the middle setting for focus which gives better results for me than the spot, and concentrates more light on the middle area but is also good for most situations.
