Hi Craig,
A guitar can feel good and play well, or not so much, but determining so is rife with subjectivity. Measurements are the objective "measure" of a setup.
Assuming all sounds right with the guitar as you attest, you should now measure your relief at the midpoint, measure your high and low E string-to-14th fret gap, and compare these numbers with stock setup (not that stock is "right" as much as it is the factory's benchmark for guitars leaving their hands to head to stores and customers).
Now you will know your guitar's baseline, from which you can now ask a proper Taylor tech (who must have the proper neck shims or the setup won't be done properly for an NT Taylor) whether he can improve upon these numbers. But even then, this assumes you want him to go lower as not everyone does.
The best setup is the right setup for the player's own preference, his playing style, and music genre. My suggestion to you is measure up your guitar, then talk to a good tech about all these factors.
