Would a Unified theory like string theory or quantum gravity be intrinsically tied to empiricism?

It would depend if the theory were experimentally or obsversationally validated; in the case of String Theory (which is a theory of quantum gravity), more accurately called M-Theory (M-Theory unifies all five variants of String Theory into one with 11 dimensions), experimental validation is out of the question. Experimental validation would require an enormous particle accelerator; the scale of this accelerator simply cannot be imagined. Observational validation is unlikely as well: M-Theory predicts that we should observe magnetic monopoles (magnets that we have are dipole, meaning that they have a North and South end); however these have not been observed and are unlikely to be observed: they are not expected to have a very high density, meaning that the universe is too large and monopoles too few in number. Although it would be great if validated, it is highly unlikely to ever happen.

How does the theory of quantum mechanics apply with string theory?
String theory is one of the leading candidates for a theory of everything, that is, a theory that unifies all 4 basic forces of nature, viz, gravity, the electromagnetic force, the strong force and the weak force. The last 3 forces mentioned above are described by quantum mechanics. This is the link between quantum mechanics and string theory. ps- If you believe in watertight definitions, then quantum mechanics is all the quantum theory till Dirac's equation. I'm taking quantum mechanics as the theory of the small as such, that is, all of the phenomena of the small from Plank till the standard model and beyond.
Is string theory the closest theory to a unified field theory?
Yes, so far it is- string theory explains many of the unresolved fundamental problems of our century, such as the opposition between Quantum Mechanics and Einstein's theory of general relativity.
What is quantum free electron theory of metal?
Classical free electron theory could not explain many physical properties. In 1928, Sommerfeld developed a new theory applying quantum mechanical concepts and Fermi-Dirac statistics to the free electrons in the metal. This theory is called quantum free electron theory.

What is the leading Grand Unified Theory?
It depends on what you mean by leading. A few good candidates are string theory, the standard model and loop quantum gravity.
What is the ISBN of Three Roads to Quantum Gravity?

How many pages does Three Roads to Quantum Gravity have?
Three Roads to Quantum Gravity has 196 pages.
When was Three Roads to Quantum Gravity created?
Three Roads to Quantum Gravity was created on 2001-06-05.
What is loop quantum gravity?
It is an attempt to merge quantum mechanics and the General Theory of Relativity.For more details, I suggest you read at least the overview in the Wikipedia, article "Loop quantum gravity".

Why is string theory so attractive to those seeking a unified field theory?
String theory attempts to unify the general theory of relativity and quantum mechanics, two prominent and proven theories that are the most incompatible. If gravity and the electro-weak/strong interactions could be combined, that would create the unified field theory or theory of everything.

What is true relativity or quantum mechanics?
Einstein's work on the Photoelectric effect, which won him the Nobel prize in 1921 was a bulwark of Quantum Mechanics. Einstein went off in another direction because of his inate suspicion that Quantum Mechanics has severe internal difficulties. Quantum Mechanics and Relativity have not yet been reconciled--but they are moving together slowly. Quantum Gravity seems to be key to the issue and may be resolved by String Theory.
What is Quantum Gravity?
In a word. No. Grand unification is also commonly called the Theory of everything. Which in a sense, there would exist an equation of a set of equations that every other physics equation can be derived from. A quantum theory of gravity would only help to better blend quantum mechanics and classical mechanics, not necessarily leading to a theory of everything, though it would be another step toward it.
What is The Grand Unified Theory?
The GUT or TOE "Theory of Everything" is the unification of Relativistic and Quantum Physics, probably via String Theory.
