What are some basic texts that someone could read to gain a working knowledge of how a general assembly would work?

Answer 1

As far as i know there is no single good text that addresses different kinds of anarchist organization - which is where this would fit.
Various sites however do have rough outlines of how different assemblies have worked - for example this on the student occupations in paris '68
"General Assemblies at the Sorbonne were carried out every night, (generally, sometimes waiting for marches, etc), and students volunteered or elected various groups into action collectives that carried out various tasks. The people within the various groups had to be re-elected at various times and could be recalled.  " (from anarchopedia)
Other places mention Argentina and of course Greece where assemblies seem to work roughly the same way as listed above.

Although it didn't get in to the mechanics of general assemblies, the outline given in Horizontalism by Marina Sitrin was pretty good, in my opinion.
