3. What's the difference between an S Trap and a P Trap?

An S-Trap drains into the wall, A P-Trap drains into the floor

An S-Trap drains into the floor, A P-Trap drains into the wall

There is no difference

An S-Trap drains into the floor, while a P-Trap drains into the wall. This means that the S-Trap is designed to connect to a drain pipe that is located below the level of the fixture, such as a floor drain. On the other hand, a P-Trap is designed to connect to a drain pipe that is located behind the wall, such as a wall-mounted sink. The difference in the direction of drainage allows for proper disposal of wastewater and prevents the entry of sewer gases into the living space.

4. When faced w/ a dripping faucet, and it is the older type (rubber washers and screw in seats), you take it apart to see the washer is ripped up some, but still intact. How do you tackle this problem?

Change the washer, only

Change the seat, only

Change both the washer and seat

Flip the washer around so the "good side" is showing

Tighten down on the seat

A good way to judge if it's the seat or washer causing the problem is this: If the washer is ripped/chewed up, or there's nothing left, the seat is usually cracked or nicked. This rips the washer apart. If the washer is still smooth, but is just indented, then it's just worn down from use. Simply replace the washer.
