Can I save files in the Launchpad on my MacBook Pro?

No, you cannot save files on the Launch Pad screen.

If you want the Pages application on the MBP, simply download the app from the App Store. It's free!

You can add the iCloud website to the Dock so it and the Pages web app are always accessible there.

Alternatively, you might set iCloud as the Home page of your browser.

What exactly is it that you're trying to accomplish here, and why?

Sounds more like you want a desktop organization tool / clipboard manager like Unclutter or Desktop Groups.

You can only put folders and documents on the right side of the dock. You can't intermingle them on the left side.

You can download Pages and not have it in the Dock. You don't need to put everything in the dock. You should trying using Spotlight for launching apps. It's very fast. And when you're not using it, it's invisible.

Unclutter is on the App Store, I believe.

Maybe it's time to upgrade...
