How does one repair car leaks from sunroof and door frames?

We discovered that our wet front passenger floorboard is wet because of drips coming in on the far right side just under the glove compartment, and also a drip coming down in the door frame on body side.  There is also a similar leak in the left door frame on the body side, and when making a sharp turn out of driveway I heard what appeared to be water sloshing in the upper door frame on the body side.  The driver's floorboard was not yet wet though earlier this month it was wet after a huge rain storm.  The sunroof has a leak in a small area at frame site.
