Call Request(), it is documented in the Intuition Manual. It returns
TRUE if your requester could be rendered. After that all input to 
your event loop comes from the requester until the user selects an
ENDGADGET type gadget or your code calls EndRequest().

DM stands for 'Double Menu'. With the routine SetDMRequest() you can
arm Intuition to display a requester of your choice when the user
double clicks on the *Menu* button.

A requester must be large enough to hold all of the gadgets in it.

Gadget Coordinates are relative to the top left corner of the requester.

>Are there any books with more complete information?

Yes, the Intuition Manual, the section on Requesters, lists the various
routines you can call that affect requesters.
