There will probably be some answers from the APEX experts, but I'll give my view on it.
You can build applications that are hard and easy to maintain. It is a very similar model to Forms where you can put all kinds of triggers and database logic in the form, or you can separate it to only have the user-interface in forms.
I would consider the same things for APEX. Break out business logic to separate packages, possible the SQL in its own packages and keep only the user-interface logic in APEX. This is a general best practice (for all development models, not specifically for APEX) as the user interface typically is changed more often than the data structures or business logic.
That way you would not end up with code pieces buried in different places in APEX, only what is needed to make the application display the way you want.
