This is how I drive a clutch...
I release the clutch with little or no gas. Once it engages I give it gas and finish letting it out. My 3.0 and my 2.4 have always had enough torque at idle or slightly above to drive in this fashion. And since the engine is not spinning fast, there is less burning of the clutch. The heavier flywheel stores extra inertial energy that can be used to get all the runnning gear turning. So the way I drive, I use the bottom end of the torque curve.

People who rev their engines to 2-3000 then dump the clutch are running in the middle-top of the torque band. Guess who is going to replace a clutch first.

I've always driven manual trannys, always put over 100,000 miles on a vehicle before I got rid of it, and the 4Runner is the first vehicle I've replaced a clutch in. Because the rear oil seal lubed the old one. In fact my Corolla has 249,000 on it's original Toy clutch.

I didn't notice a lag in acceleration at highway speeds although the laws of physics dictate that there would be. Keep in mind, the TRD flywheel is only 5 lbs heavier. I've heard of other flywheels weighing from 8-10 lbs. If you do a search for some of the previous posts, it seems that folks with the heavy ones disliked them because of the lag in acceleration. I think the TRD is a good compromise. You forget it's different because it works so well.
