Can I import anything other than data such as, tables, grids, pages, views, etc.?

See this article here for more information: Importing Records.

Pages, Views, and Other App Elements

Currently, there is no functionality available to import pages, views, or other app elements into your apps. However, you do have the option to copy/duplicate pages and views within the same app, allowing for easier replication.

The following articles provide more information:

You can also copy an entire app with its pages and views as the starting point for a new app.  Otherwise, you must manually recreate the pages and views in your app.

Please see our Managing Your Apps article for additional information.
