Suppose that I want to kill my own Grothama, All-Devouring in order to draw cards. It sounds like one way to do this is to fight it with my own creatures, in the process of attacking an opponent. If one of my own creatures fights Grothama, All-Devouring and survives, then continues into combat with my chosen opponent, does it go into combat with the damage that it sustained from Grothama? In other words, does pre-combat fight damage carry over into combat?
Can I use a wrath or board wipe to kill my or my opponent's Grothama and draw cards? My guess is that cards like Hurricane and Crypt Rats would work, but cards like Wrath of God which "destroy" instead of inflicting damage won't. Is this correct? Does "destroying" a creature just send it to the graveyard (without inflicting damage)?

Yes.
Once damage is dealt to a creature, it stays marked on that creature until all damage is cleaned at the end of turn (in the Cleanup Step), or until the creature regenerates or leaves the battlefield.

Destroying a creature just causes it to be put on the graveyard. It's not damage.
Also, notice Grothama doesn't have Flying, so it's not hit by Hurricane (unless something else gives it flying first).
I was told that Temur Sabertooth can be used to repeatedly draw cards from nonlethal damage to Grothama, All-Devouring. The idea must be to use Temur's activated ability after Temur inflicts fight damage on Grothama, All-Devouring, returning Grothama to one's hand and giving Temur indestructible so that it doesn't die to Grothama.
Is this possible and, if so, how does the activation of the ability have to be timed?

This doesn't work alone. Temur Sabertooth will die from fighting Grothama before you can activate its ability to give it indestructible or Grothama will no long be on the battlefield to fight due to having been returned to hand for the Sabertooth's ability.
The basic concept of returning Grothama to hand to draw from any damage dealt functions but you need a way for the Sabertooth to survive.

I just realized that Temur Sabertooth's activated ability doesn't have a tap sign. The strategy being referred to must be to activate Temur's ability once, sending an unrelated creature that you control to your hand. You then fight Grothama, All-Devouring with an indestructible Temur, and finally activate Temur's ability a second time, returning a damaged, but still living, Grothama to your hand.

Does that make sense?
