I'm in the same boat as you were in; mine's stuck in a bootloop; I don't know if I got s-off though. How did you manage to get yours to stop bootlooping?
I had to reflash the ROM, and as a safeguard, I cleared the cache and the dalvik cache, and rebooted. I didn't lose any of my data when I reflashed it. You can check if you have S-OFF by booting into the bootloader, and at the top, it will say either "S-ON" or "S-OFF."
