The other questions get a bit more involved.
Impulse Response files, at their simplest, are just a Wav file that records the response of a room or a piece of gear when it is stimulated by a loud sudden sound (an impulse). This can be a gunshot, a clap, 2 boards being slapped together, or a short burst of pink noise.
In the case of a room, the echoes and reverb caused by the sound are recorded into the impulse response wav file.
Now you can apply the reverb and echo of that room to any sound by loading the IR file into a plugin (such as ReaVerb) and running the sound thru the plugin.
You can do this for any 'linear' process - reverb, echo, guitar speaker response, amplifier coloration, equalizers. It won't work on anything with distortion or compression, though since those are nonlinear.
They are installed like any other file - create a folder, put the file in it. Use the plugin to browse to the folder and load the IR file.

Would it be possible to apply an IR in a subtractive manner? I'm thinking of how nice it would be to digitally deaden a crappy-sounding room. Kind of like ReaFIR in subtract mode, but for reverb, not noise.
