Hi Shay-A,
Here are links to the user guide that discuss these things:
Models
Helpers
Libraries
If you want to create your own libraries, this user guide entry will help you with that:
Creating Your Own Libraries
Hope this helps,
Randy

A model is the only entity that should be connected to the 'raw' data : sql queries, file content, screen scraping.
A library and a helper manipulate the data passed to them by a model. The difference between a library and a helper is that the libraries are used in controllers and helpers are used in the views.
This is a black and white view but as you know the real world isn't black and white so one function can be handled by another entity. For example a rss feed aggregator library. The feed content should be fetched by a model and passed to the library.
