under drive pullies
What do you mean "hows the idle?" Idle quality is not affected. Charge at idle wasn't affected on my car either, but I have my idle set to 950 rpm. ASP recomends 800 rpm for their underdrive crank pulley, and 950 rpm if you use both the crank pulley and the underdrive alternator pulley. I've never heard of anybody having a charging problem, though.
If the idle is too low it will not charge properly while the car is at idle. I am sure they recommend 800rpm for a reason and they did not just randomly throw a number on the table.
I would definately bump up your idle alittle bit if you are going to go with the pullies ...

It shouldn't be much of a problem as long as you don't leave the car idling for too long, and then don't drive it. Once you start driving it, it will return to it's normal (or close) charging.
As far as the underdrive and stereo ... it depends on alot of things. I have a really large stereo system, so I have chosen not to install the underdrive on this car (had it on my last) ... however, if you have a smaller one, or if you get a powercap or some other devices such as that, you should be fine.
