Keep an eye on the aperture, shutter and ISO settings Keith. If your camera has auto ISO it might be an idea to see how you get on with auto ISO selected but also keep in mind that higher ISO's can give more noise. If you don't like auto ISO you can always increase it manually to get the exposure you want with your selected aperture and shutter settings.
Also, many people tend to manually focus when doing macro as with AF the camera will focus on something but that something might not be the best choice. What you could do is use AF to get you near and then fine adjust with manual focus.
Actually... another little project for you could be to use all the ISO settings and see at what point the image starts to be affected by noise too much.
Good luck with it
