Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Group is the main group and can be only one. 'Suplementary groups' is a place for all other groups (there's a limit on number of groups for one user, but it's hard to get to it) . There's not big difference.
What o you mean when you write 'point to some place'? Home directory? Beeing in a group means you can access files/directories with group equal to one of your groups (of course, the permissions may be different, for example when owner has read/write/execute, group can have read/execute and other users may have no access to the file).
