Your camera looks like it’s pretty decent, and should give good results for your purposes.
However, even if you have no interest in photography as such, for what you want it really would be a good idea to learn some of the basics, for example, Jason mentions the white wall fooling the camera’s exposure control, so you need to know why that is, and what you can do about it.
I can’t give you references, my knowledge of photography comes from the days of film, and although the principles are the same, a modern book/online tutorial/etc. will be easier to apply to your camera. You can always skip the bits about taking portraits or whatever, though the basics of composition are worth knowing.
And yes, don’t use the flash, you’ll have loads of problems with reflections, burnt-out bits, etc. with it.
