Yes that is the right thread for voodoo. I believe Gunnermike53 has an explanation of what voodoo is and how it is different from non-voodoo in the thread. I am not knowledgeable when it comes to voodoo, so I couldn't tell you. As far as getting comfortable flashing you can get some practice by downloading different themes and switching back and forth between them. No need to do a wipe with flashing themes so you get practice simply navigating through cwm to install things. I like Adrynalyne's superclean ROMs, so I get plenty of practice flashing roms just trying to keep up with all the versions he puts out. I don't think there's anything you can do to your phone that someone here cannot help you fix. So play around and have fun.
Great, I'll do some reading up. It looks like (and I could be wrong) that Voodoo uses a different file system (EXT4) than non-voodoo.
Do you have a link to Adrynalyne's superclean roms? I'm going to start flashing themes and see what happens (other than more android addiction!
