Re: Easiest way to get data from a model (better way than $model->data['modelname']['field'])?

One slight change: you're $model param is superfluous. There's no need
to pass the model as this is the AppModel. Just use $this when
referencing it.

I'd also check if $this->data exists before doing anything.

OK, one other possibility:

public function data()
{
if (empty($this->data)) return null;

$res = Set::extract(
'/' . implode('/', func_get_args()),
$this->data
);

// ...

return $res;
}

I didn't return immediately because I know that, in some cases, $res
is going to be formatted in unhelpful ways. So some further work would
be needed.
