jBox runs entirely on the client (browser). jBox uses Liveconnect to 
allow communication between client-side javascript and the Java applet.

At this time, jBox does not distinguish between right and left mouse 
clicks. Phpmapscript runs on the server, so I am not clear on how that 
would work.

Yes. The only formal documentation is in the HOWTO on the mapserver 
doc's page. There are also a lot of comments in the Java source.

Primarily jBox was designed just to provide the screen coordinates of a 
rectangle defined by a user's mouse drag. Depending on mode (browse or 
query) mapserver will use the rectangle coordinates to zoom or do a 
spatial query.
