If i used a ruby tablet of courage (it says it resets weapons attack value and replaces with a new one) and made a stone with it then used it with a weapon, could the attack power turn out to be lower or does it always go up?

Could go lower. It resets to any (%) between 0 and 100.

Also, there is a chance that another white stat, or even a blue stat can be raised or lowered. Use the 10% stones on gear that has good stats to start with. And use the 20-30% ones to pimp out drops and SOS that have not been pimped yet.
