As I understand it, it is mandatory of you're using PHP 4, optional
but good practice in PHP5.

It is arbitrary - it could just as well be "$this->set('FooBar',$this-

in your View - it will contain the value of the second argument to the
'set' function, in this case the return value of $this->Post-

It refers to the model which is referenced from your controllers by
the name you assign to it - in this case, 'Post'
Always adhere to the naming conventions to make your life better.

The view doesn't have access to the model directly. The controller
can query a model and pass this information on to your view. Here,
'Post' refers to an array element ($row[]) which (following naming
conventions) was given the name of the model that the information came
from.
Since your questions relate to the "var $name = " in your models, I'd
say don't worry about the existential distinction between a model and
it's name. Once you get your models set up, you'll never look at them
again anyway. If you follow naming conventions for your tables,
models, etc, Cake will always know what you're referring to.
