What does the ECT/PWR button do?
So what exactly does this button next to the shifter and all do? The pedals feel lighter whenever I activate it, MAYBE a tad quicker too? Does it advance timing? Info please?

"norm" is considered a type of "gas conservation" mode while "pwr" simply makes the shifting pattern more agressive. It doesn't give any extra horsies however.
ECT = electronically controlled transmission

Follow up questions:
- is it okay to switch modes "on the fly"?
- is it okay to run PWR on the highway at 80mph? (I still get overdrive, right?)

At least that's what I've been told.

Don't know if it's safe to do it on the fly. I wouldn't suggest it, it's trying to change the rate at which it switches gears so if you're changing it mid gear shift than you could really mess things up. Flip it when it's stopped.

The thing you're thinking about is Electronic Throttle Control System with intelligence (ETCS-i), which links the accelerator pedal directly to the engine computer and responds accordingly. Basically drive by wire on newer Lexus models (IS, 01+ GS, etc)
More proof? Here's a link from Lexus with the definition http://www.lexus.com/models/glossary.html?entry=ecti
Shifting ECT on/off on the fly is just fine, I've done it since 1983 on all sorts of Lexus / Toyota with no problems.
I often leave my cars in Power for a more fun driving experience, but it does have a cost. 1) Gas as you mention and 2) the higher revs can put a bit more wear and tear on your car. Not something I personally worry about - worth the tradeoff for the extra umpf

My OD is ALWAYS on. I like it that way. And as far as the pwr button on the highway at 80mph, yes, I actually recommend it. If I'm traveling over 45mph for any extended period of time I always have my tranny in PWR mode.
