>gravitons are used to patch up

There is no "one" idea of the gravition. There is no "gravition theory", it is just a collection of loose ideas used by some to attempt and incorporate gravity into quantum field theory (by making a quanta of gravity).

The idea that "gravity" needs to be incorperated into QFT is a huge leap. It is easier (and probably more fruitful) to just take QFT and put it into a fucked up metric (as we have tons of experimental evidence suggesting this technique). This is essentially how we introduce gravity into all other branches of physics, why not QFT?

However, The mathematics with doing this, are very difficult, and basically the only thing hampering this idea so far. We suck at math, we suck at dealing with infinities. We has a similar problem when we first invented QFT, but eventually over came it. The problem now is more difficult, but eventually can be overcome.

>Was the original theory wrong?

Newtonian Gravity. It wasn't wrong, as it works. It turned out to only be an appoximation of GR, hence it only worked in certain cases.

>How can you derive two different sets of equations from the same axioms?

How can you derive different branches of mathematics form the ZFC axioms? A great amount of math (more then the average person encounters) are based off a few axioms (ZFC-axioms). Yet, they can be used to reproduce the foundations of most branches of mathematics. Physics is similar.
Using only a few fundamental equations and procedures, you can produce Classical Mechanics, Special and General Relativity, Quantum Mechanics, Quantum Field theory, etc.
