Okay...
First, as far as I can tell from the specs the camera does not, repeat, does not, have an XLR input.

What you are doing is plugging a condenser mic with an XLR connector to a camera with a 3.5mm minipin audio input port. The mic runs on a battery so at least you don't have any phantom power worries (for now). What you need is an impedance matching transformer that will also route the mic signal to both channels of the camera. The LMT-100 will do that for $20.

If you're currently using just an XLR to minipin adapter (no impedance matcher) your sound should get a bit cleaner with better levels if you get the LMT-100 or something similar.
The next step would be either a mixer to hook up to the camera like the juicedLink CX231 or a dedicated digital audio recorder. Since they are about the same cost I would recommend a digital recorder like the DR-100, or something substantially better like the PMD-661, HD-P2 or R-44.
