Answer

I agree that in many cases you could translate it as "mejor... blablabla". However, in this particular sentence I'd go for:
"¡Más te vale llamarme cuando llegues a casa!"
Depending on the tone this may sound a little harsh or slightly aggressive, but I think it conveys better the meaning in English.
Regards!

Answer

I would say: Es mejor que o Es conveniente que ... and then Modo Subjuntivo

Answer

another option could be : "¡Será mejor que me llames cuando llegues a casa!" with a threatening tone.

Answer

Hi Don,

Lidia was right

I also suggest:

"Es mejor que tú..." me llames al llegar a casa.
or "Mejor tú.." me llamas cuando llegues a casa.

Happy Holidays!

Answer

Hi, Don!
Here is another option:
Mejor llámeme cuando llegue a casa (imperativo - formal treatment)
Mejor, llámame cuando llegues a casa (informal)
