newbie learning to use packages

Hello all...

I am new to BSD and the package system, and have been doing a lot of reading 
lately.  It looks like the default installation directory is /usr/pkg.  So far 
so good.

Do most people leave the installed components here and update your path and 
manpath?  Do you use pkg_add's -p option to specify the location, and how would 
you know ahead of time to know what that location should be?  Do you move 
binaries to an appropriate (/bin, /sbin, /usr/bin) binary directory, man pages 
to an appropriate man page directory, and so forth and skip changing your path 
and manpath?  I am not sure which way is best.  Some practical real-world 
advice please!

How/where do I get shared libraries required for new packages if they are not 
already on the system?

Thank you,
Tim
