It sounds like you have one of these:
http://www.eastcolight.com/telescience/pr_9940.php
It hasa 60mm objective, a 700mm focal length, and comes with 4mm, 12.5mm, and 20mm eyepieces. Lets begin by putting aside the barlow lens and the erecting lens. The erecting lens works best for terristial viewing and the barlow lens is not needed on this size scope.
Begin viewing with the 20mm eyepiece (35x), and find and center your target. Adjust the focus so that it is as sharp as you can get it. Now watch the object move across your field of view. Try adjusting your scope to keep ot right in the center. Once you get comfortable doing that replace the 20mm eyepiece with the 12.5mm eyepiece (56x). Notice that the object seems to be moving faster, it is much harder to keep it centered. But, learn to do so and practice until you are comfortable.
Finally replace the eyepiece with the 4mm lens. This should take your magnification up to 140x. Try to sharpen the image, but be aware that 140x may be too much for your scope or too much for prevailing conditions. If it is not really sharp then go back to the 12.5 eyepiece.
