DOES CHANGING GEAR OIL HELP IMPROVE CONDITION OF GEAR

My gearbox makes noise when I go into 3rd gear and continues when I am in 3rd gear and also when I go into fourth. If I change the gear oil do you think there will be any improvement to the gearbox.
also my timing chain makes noise when I have driven for for a sustained length of time, or say after an hour or two of intermittent driving it starts and continues but I hear no noise when I go on short journeys at the beginning of the day. Does it need to be changed immediately or can I wait till the time when I hear noise continously?
