Easy Life Potions:
Go to an area that gives Life potions and collect one. If you then leave the game and return to the location where you picked up the potion you will find another one there. This can be repeated as many times as you desire.
Removing Quest Text from Chat:
This can be easily done by opening the 'Sound' options and unchecking the 'Show Quest Dialog in Chat' option that is located at the bottom right corner of the screen.
