Bare with me as this is a LONG post. I spent about 10 minutes with GarageBand today and spoke to a high level product specialist who answered some of my questions. Some things AREN'T listed here as they have been covered on this forum already.

Instruments:
The system is very modular. You can pick a pre made instrument, or you can choose one, change the settings (including the actual instrument of choice) and save that as a new instrument. So you have a set of actual instrument types, and then you have a set of instrument presets that have all the settings you like for that instrument. These you can change and save as much as you want.
In each preset window, you can change things like Instrument (as mentioned earlier), Compression, EQ, 2 Effects (including Audio Units), Echo and Reverb. So all this can be saved

... and it goes on....
