Wait you are going the right way right?
Shoot some PB on the bolt and let it sit for a while.
Then take your breaker bar and find some heavy square tubing to use as an extention, then go to town.
Also use an impact socket on the bolt, I have seen cheap chrome sockets explode when used in high torque apps.

I wouldn't even try it with a 1/2" breaker bar, they are not rated that high. I used a 3/4" breaker and had both feet on the end of it. You do not want any part of your face near the bar when you're putting that kind of force on it -- I know too many mechanics with no front teeth and broken noses from this kind of stuff...

Also worthy of honourable mention, the support crew: Mr Collapsible Saw Horse, held up by associates Mr and Mrs Jack Stands. (The support crew gave me something to brace my foot on to get some purchase on the push.)

So: What are the options for removing the alt/compressor pulley? Gear puller the best? If so, what size? (6", or bigger?) How many jaws? (2 or 3?)

A gear puller would be best if you can fit yours on there. One time the pulley was stuck and I didn't have my puller handy. I made a puller using m6 bolts and screwed the bolts into the bolt holes in the pulley.
Yummybud, the torque wrench I use for loosening stubborn bolts is a cheap one I don't care about. I only use it for torquing lug nuts and breaking things loose.

Use a good sized pry bar, and gently start wiggling at the top, then the bottom, then the top, bottom, etc. Sometimes they come right off, other times it takes 15 minutes of wiggling before it will start to break loose.

Thanks, Doc -- "wiggle, wiggle" did the trick. Took about 15 mins, too...
It's so valuable to get advice like this -- no way I would have tried that if I hadn't been told it would work.
I found in my case a thin offcut of wood on the back cover to lever the bar on helped -- protected the plastic cover to some extent (which already had a crack in it near the bottom, as I discovered), and positioned the tip of the bar closer to the back edge of the balance gear, giving better clearance of the timing belt rollers.
