What if you have several other models associated by belongsTo (or any
other assoc)?

The key is the model alias, actually. This is usually the same as the
name. And, if you've got a model associated with itself, you'd do:
(say, for a User model)
$this->hasMany = array( // or other assoc
'Friend' => array(
'className' => 'User',
....
So, when you want to fetch a User's Friends, you're really fetching
other Users. But you refer to them by the alias to avoid confusion
(both for yourself and the DB query).

Meh. Faster, how? It's a few extra keystrokes. And, besides, if all
your other data is going to come to you in an array, why not have it
all there? Besides, having it all together like that allows for
manipulating it with Set class. If some data was in an array, and
other inan object, that wouldn't be possible. Not without adding the
object's data to an array first. And that'd be a bunch of extra
keystrokes.
Personally, I've gotten into the habit of always fetching data into a
variable named $data. No $user = $this->User->find(...) or $post =
...Because then your constantly looking for data in
$user['User'][...], which seems a bit dumb. Or looks that way. But
$data['User'] makes perfect sense.
