Can't see Jupiter/Saturn with RX-9 telescope
I would not feel too disappointed. The RX-9 is not a large or powerful telescope (sorry) and is therefore not capable of huge magnification without loss of clarity. The largest practical magnification for this scope in a dark-sky site would be about x225, which would be about a 4mm eyepiece. Such an eyepiece is in fact difficult to use unless it is a very expensive wide-angle type. They can cost $500 just for the one EP. The EPs you got with the scope will not be in that league, being cheap "Plossls".
If you are in the suburbs, you will also have a lot of light pollution, or sky-glow, and this makes it even more difficult to see a sharp image. The best image available may not be enough to see the bands, let alone the GRS. In the burbs you may only be able to use a max magnification of x90 , or about a 10mm EP.
Bear in mind that ultra-high magnification for visual observing is pure advertising nonsense, for all but large observatory scopes. Those lovely pictures you see are the result of long, heavily processed time exposures with a sensitive camera. You won\'t see that with the naked eye, especially in the burbs.
In addition to all that gloom, the GRS is not always facing us here on Earth. Here is when you can expect it to be visible
