My answer is no to all four questions. I have washed my engine bays on cars many times and have never has a single issue. I do not shoot a high pressure hose directly at the alternator, the engine computer or major electrical connections or other control units, but it will not hurt them to get wet. The main thing you do not want is to shoot water into the air intake. So depending on what you remove, and how the intake is designed on your engine, a plastic bag and rubber band may be needed.
