A short is a direct connection between positive and negative with no appreciable resistance. The result is very high amperage, a lot of heat, smoke, and fire.
A hot wire is indicative of either a resistive load (usually a bad connection that has a high resistance) or a wire that is too small for the load that it is carrying, thus it presents as a resistive load.
The typical, modern-day wiring loom has wires that are only just big enough to carry their intended load. They are typically smaller than they should be and the wires that carry a high load will get warm. This is typically the headlight circuit on a motorcycle. The problem with this is that the under-size wire doesn't leave any margin for error; it has no excess load-carrying capacity in the event of a poor connection.
To answer your question, yes, some warmth is normal in the headlight circuit. None of the other circuits should be carrying enough load that they would get warm. While you may feel a warm wire, it should not be uncomfortable to touch.
A popular modification, which improves lighting on the Gen 1 bikes, is to re-purpose the headlight wiring as relay triggers and install a decent lighting sub harness with larger wiring. There is then less voltage drop and more voltage available to the headlights.
Adding grease doesn't do anything to improve the connection. Once the connection has been properly cleaned of corrosion, curing the bad connection, grease will serve to prevent further corrosion from happening.
