I'd say that picking up something within reach should be a half-action in a non-melee combat situation. In a melee combat situation I'd make the person attempting to pick up the object make an Agility (or Dodge or Acrobatics) test or incur an attack of opportunity. After the item is in hand then it'd have to be readied as normal. Or, if a character has Acrobatics, let them make a test against Acrobatics to see if they can pick up the item as a free action. Modifiers could be used depending on the situation and severity of battle. Perhaps when engaged in a melee battle with a particularly rough opponent you'd have to make a Willpower check to see if you'd even be able to go for something on the ground.
