In my first playthrough of ME3, I played mostly Paragon but with some minor Renegade choices along the way, so I ended up with a maxed reputation bar with approximately a 90%-10% Paragon/Renegade split. This means I was unable to unlock the final Paragon (or Renegade) dialogue option near the end which is required to
convince the Illusive Man to shoot himself.
Apparently, unlocking that dialogue option requires a 100% Paragon (or Renegade) score.
I've just started a New Game Plus, and since the Paragon/Renegade ratio appears to carry over, does my previous Renegade choices mean I'm already doomed to fail to unlock that option even if I only make Paragon choices this time around? Or do my choices in this playthrough overwrite the ones I made in the last one?

You cannot get rid of either paragon or renegade reputation. The ratio may change, but getting one does not decrease the other (though it may seem that way with a full reputation bar).
That said, I find your claim that one must have 100% x and 0% y reputation to succeed at the last check highly debatable. The reason the introduced reputation was to stop penalizing players for making decisions against their "alignment".
