But you forget about what gravity is. It is the force of concentrated mass in one area attracting another bit of concentrated mass. Since the sun would be expanded, still containing roughly the same mass, it will have less of a gravitational pull. Since the expansion would be slow, it would not force the earth away so it would just slowly push the earth out of it's self. Unfortunately, not in time for it to melt away to nothing.

But you also have to remember the mass it gains as it does grow. Space may be mostly empty, but not completely. The earth gains 10 tons in mass each year from cosmic dust alone. The sun will have gobbled up Mercury and Venus by the time it gets to us.

Yet it is hardly enough to affect it's already vast size. I doubt it would be enough considering it could hold millions of earths in it we are only 1% of the sun's volume and only 1/332,000 of it's mass.

True. However, it is enough to throw it into a decaying orbit, to say little of how long that will last before it's been burned up completely. might not even make a full revolution.
General Omega:
With the smaller gravity, the earth might have enough speed to break free of the decaying orbit it is already in and move slowly out of the orbit it is in. The problem is that it would not make it out. Hell, i would not give it a season before the earth completely evaporates.
