I wouldn't recommend any supercharger,v6,juuwes etc etc at all,all there tweaks can be done manually and give yourself the full control over tweaking but I'm not getting into this......
Phone will heat up whilst using / charging and is quite normal unless your getting excessive overheat!! Then probably got too much running as mentioned already. Apps scratch has mentioned are good,autostarts is really good for eliminating background startups of unwanted processes and one scratch forgot which he told me about is fastreboot (pro or free are both good) for quick system memory gain,kind of like a task killer but way way better.
I would uninstall all your not priority apps and wipe dalvik cache after, lol I've got no more than 15 downloaded apps installed.(more than 150 backed up for when/if needed.
