What is the advantage, cost, etc, of purchasing a set of dedicated wintertime wheels and TPMS sensors vs just simply having a tire shop swap tires twice a year..?

Reasonable question. The price for four BlizzaK Tires mounted on new steel wheels is about $650, and the TPMS monitors are $116 for a set of four (Honda sensors are inexpensive compared to many other brands for some reason). So it is about $775 for the whole shooting match including sensors.
The Blizzak's alone are $430. Mounting and balancing around here is about $20 per tire.
So here are my options and the prices:
Dedicated tires/rims and no sensors: $650 (one time charge-I change these myself) Disadvantage- either cannot turn traction control off, or --as you suggested--traction control is always off if system sees no TPMS sensors. I think that ABS still works in this vehicle under these conditions.
Dedicated tires/rims with sensors: $775 plus $80 twice a year for the Honda guys to reinitialize car's computer each time for the alternate set of sensors (winter vs summer tires).
Tire shop swaps tires twice a year: $430 plus $80 twice a year (this time the same $80 is spent on the tire changeover instead of the sensor re-programming)
I guess I wasn't considering this because it is so convenient for me to just switch out my own tires in the driveway with a floor jack vs taking it to a shop and waiting. Also, my nice rims don't get mucked up in the winter.
Thanks for the comment about the possibility that traction control is already disabled with TPMS light on...I never thought of that and will research this more and comment back. Just read the post today.

Where do you buy the tires for $430 for Blizzaks?

1) You can get cheaper winter beater wheels.
2) You can get -1 or -2 size wheels. With those, you will need tires with taller sidewall which give better traction in snow and slush. Those are cheaper too, and the difference is significant for most brands.
3) I am not sure how much it costs to swap tires, say $50-$80. That's $100-$160 per year. Over a few years it adds up. If you keep your vehicle for a long time, it's proably cheaper to get the second set of wheels. Swapping wheels is something I can do myself in my garage, it takes me about 40-50 min., probably less than driving to a tire place (with 4 dirty tires in the trunk), and have them balance and swap the tires.
4) All that repeated swapping can't be good for tires.

"F/awd system could be easily modified"
My 09 HL one wheel drive is nearly useless in the snow and I am wondering how one would go about modifying it as you described using a switch to over-ride the the clutch.
In your opinion would this help substantially or is it just wishful thinking?
I am pretty handy with a tool and would seriously entertain this idea, realizing of course (hoping really) that it would be like locking in a tranfer case.

Sorry, but I was referring to the NEW F/awd system now used in the Sienna, Venza, and RX350. Those have an electromagnetic clutch just forward of the rear diff'l that is used to dynamically apportion engine torque to the rear drive.
In those a simple switch might be used to fully engage the rear clutch provided that there is absolute certainty of a non-tractive, slippery surface.
Basically a "part-time" 4WD system.

2003 Toyota Sequoia 4X4
Is there a way to override the TRACS and VSC system? I was heading up a muddy slope and it felt like the rev limiter kicked in and I couldn’t power up the rest of the way – it felt like it was trying to get traction and slowing the revs of the motor to do so.
Am I able to flash my ECU, pull a fuse, or snip a wire? Did I just buy a soccer mom taxi?
Thank you in advance for any insight or explanation anyone can extend.

In a true 4X4 if you lock the center "diff'l" that automatically disables TC and VSC. Sounds like in the conditions you had you needed to be in "locked" 4X4 mode.

I am looking for a simple explanation describing the applicable conditions (when to use each and why) for using the (1) Auto LSD System; and (2) (when and why) to disable VCS or A-Track. This will sound dumb, but the Owner's Manual I think needs some interpretation to become clearer...Trac Off mode, Auto LSD mode, VSC off mode. Am I supposed to advance from Auto LSD to VSC OFF mode when I am trying to get unstuck, which I seem to be reading is a 2 -step process? Am I close to understanding this?

The base problem arises from the fact that selective frictional braking is used to implement Trac, LSD, and VSC. If a condition requiring consistent, continuing, selective braking were to occur and the engine not be automatically dethrottled you would end up with warped brake rotors soon thereafter, or possibly engine failure of the drive train due to the extreme stress involved.
Since the driver cannot be trusted to lift the gas pedal to the point of "feathering" when one of these modes activates the system does it automatically for you.
So the only method for getting unthrottled wheelspin as a last resort to get unstuck, etc, is to disable ALL of these functions.
