So creating the Bit.ly link is just one part of the request. In that
case, go with a component. Save the the shortened URL the component
returns to the controller into the DB and include it with whatever
else you're responding back to the client.

It looks like both the YT and Bit.ly stuff should be handled by a
component (but more on that below).

No. A component is a class that your controller uses. They can either
be inside the app/controllers/components or the
app/plugin/your_plugin/controllers/components dirs. The latter would
be for a component that is used solely for that plugin, whereas the
former could be loaded by any of your other app's controllers. An
example of that would be your own EmailComponent, an image handler,
submitted html content cleaning, etc. Anything that doesn't require a
full-blown plugin (eg. needs a model, controller, component, etc.) but
that could be used by one or more of your controllers is a good
candidate for a component.
Vendors, OTOH, are classes, or collection of classes, that are not
written with the Cake framework. Things like the YouTube API,
PHPThumb, etc. The way that you load them is with with App::import().
To use a vendor package with your own component you'd do something
like:
-- snip --
App::import('Vendor','HTMLPurifier'
,array('file'=>'htmlpurifier'.DS.'library'.DS.'HTMLPurifier.auto.php'));
class PurifierComponent extends Object
{
-- snip --
Basically, you want to load whatever class is necessary to use the
package. Here, the component acts a wrapper of, or interface to, the
vendor package. So you'd include some methods for accessing the vendor
class' methods with your controller.

You certainly could do that. But I think it'd be better to use a
component and have that return the result tothe controller, which
would then save to the DB and set vars for the view. So you could do
something like:
$shortened = $this->Bitly->shorten($this->data['YourModel']['url'];
Where $this->Bitly refers to your own BitlyComponent.
I hope that makes sense. I gotta go stir my chili!
