I prefer TheisticSatanism as a website to visit, over JoyofSatan. The information is generally presented a lot better.
In any case, while I can't really say I'm a Satanist in any degree, LaVeyan or Theistic, I do take a good interest in Theistic Satanism (and LaVeyan, though I've done more than a fair share of reading within that regard already) and so, if you wish, you can also contact me, though I'm not sure if I could be of much help.
There are also a good few books on Theistic Satanism out there (and some of them are ones I own, by chance!) that could guide you to your answers, though, keep in mind; every Satanist will probably have a different perspective on many of the questions you may wish to ask, so don't take any answer you hear to be objectively true. :-)
