The second problem is indeed probably a socket. When you change it, here's a method to avoid doing a splice - which could lead to other problems down the road: (The wires are in a wet location and doing a water tight splice is not a fun thing.)
- Take note of the order of the colored wires going in to the old socket.
- The socket has a body and an insert in the middle. The insert holds the bulb. Take a screw driver and pop out the insert in the old socket. The body will probably break apart - that's OK. When you do that, the wires will pull right out of the body. They will have connectors on the end, which receive the insert and they will probably be in good condition.
- Carefully remove the insert from the new socket. (You don't want to tear the new one apart!) You should be able to re-assemble the new body and insert on to the existing wires.
