you can use any of them. there is no primary or secondary link, there
equal.
There is also something called symlinks, much like those Win-things
(don't
know the English name, probaly link aswell, or maybe connection).
For most practical purposes they can be treated like normal files
aswell.
(they show up in light-blue with ls --color )

The directory you try to mount to does to have to exist.
eg
mkdir /c
mount /dev/hda1 -t vfat /c
Beware, if a device is not mounted the directory does exist as a normal
directory. You can write files to it just as normal, but when you mount
a device to the directory all the files in the directory are hidden.
easy mistake
/floppy #not mounted
cp FILE /floppy #file in directory /floppy
ls /floppy # the file shows up
..
.. #later
..
mount /floppy # the floppy drive is connected to floppy, the original
contents of
# /floppy are hidden in favor of whatever is on the
floppydisk
ls /floppy # where is FILE?
umount /floppy # unmount the floppy again
ls /floppy # FILE is back
