I use something like this:

But mine's 1.5 cfm, (this one is about 0.8 cfm).
It's a beast, but it sure aerates the crap out of the wort. I had the pump left over from another project, (darkroom active air filtration system that I had more fun building than using). I attach tubing to the pump, and a racking cane to the tubing, and drop it into the wort for 20 minutes. I usually have a foam puddle 2 feet in radius around my carboy by the time it's done, but that sucker is AERATED.
More simply, you can pour through a funnel, as suggested, or get something like this:
A wine degasser, which you attach to a drill, stick in your carboy, and whip the crap out of the wort.
Finally, as for hot break, some don't even care, and dump it all in.
If you don't want to dump it all in, (I don't), you can whirlpool, where you stir your cooled wort around the boil kettle until it makes kind of a whirlpool/tornado, then let it settle for 20 minutes. All the crap should collect at the center, (though it never does for me), and you siphon from the side.
