How do I keep my tube amp in the best of shape, in good working condition? I sometimes turn my amp on before I plug it on, is that a good idea?

Just use it from time to time, and always keep speakers connected when power is applied. Don't run a signal through them with the speaker outputs open. Keep them in a good environment free of large temperature changes, dust and debris.

What happens if I do run a signal through them with the speaker outputs open?

The voltage across the plate rises very high. It can exceed the maximum plate voltage rating in some cases. Certainly don't apply a signal to the preamp inputs with gain turned up if there is no load.
