I see the kit you bough includes a tripod, tripod allows you not to use flash, wich makes for a much better photo.
the main probles when shooting 6mm pics is that everything gets out of focus fast, and with a tripod you can get around that, so:
If your camera has a "priority to aperture" mode, set it in that mode and choose the smalest aperture size aperture (f-16 or f-22 for most cameras) , in most cameras this is the letter "A" or "Av", this has the effect of increasing your "Depth of field", wich simply means you keep more of the photo in focus.


The other thing you can do is set your photo quality to maximum and take the picture further away from the miniature than you normally would, then you crop the excess in photoshop or other image editing software, this magnifies the same effect above, you get even more of your photo in focus because the camera is further away from the miniature.
Also you should set the timer delay for 2 seconds, and take all the photos with the timer delay, this is because the camera shakes when you press the button, and the 2 seconds delay allow it to stop shaking and take a very sharp photo.
Then after the machine is i the tripod and pointing at the mini, set your focus to manual focus, and set your focus manualy. If you find it dificult simply measure the distance from the lens to the miniature with a ruler or tape, and use that value for the manual focus.
and thats it, there is a lot more that could be said, but this is the really important stuff to get a good photo.
