All these issues are related to vacuum. As a starting point, this is a general vacuum diagram for your car:

If you look at the engine, you will see a large vacuum line that rums from a vacuum pump on the front of the engine to the brake booster. There are a number of smaller vacuum lines that branch of the main line to the tranny controls, the door locks, and the fuel shut-off (though the ignition switch). A leak anyplace in the system will cause a lack of vacuum that will effect everything. If you search this forum on "vacuum", you will find lots of detailed discussion on how to track down leaks. In general, if can narrow down the leak by plugging one branch line at a time until the symptoms go away. When you find out what part of the system has a leak, you can keep chasing it by isolating branch components and looking for obvious leaks. It's not difficult, just tedious.
