If you're having fun (like me) using Flash Catalyst there's this useful article by Andrew Shorten about "Adobe Flash Catalyst best practices":
In this article, Andrew'll provide some hints and tips that will make it easier for you to move design assets from Illustrator to Flash Catalyst in a structured way. He'll also highlight some best practices in Flash Catalyst that will ensure you achieve the right result and minimize re-working or re-structuring your assets once work continues inside Flash Builder.
This is the list of best practices given by Andrew:
Illustrator's Best Practices for importing artworks in Flash Catalyst:
Plan your Illustrator file structure
Design on a single art board
Give everything a name
Don't link to external image files
Mark duplicated component assets
Use "create outlines" for text with filters and effects
For data list components define a single element
Don't define all component states in Illustrator
Flash Catalyst's Best Practices:
Use "Save as copy" on a regular basis
Undertake tasks in the right order
Use optimized graphics
Consider component reuse
Define meaningful state names
Rename components in the Library
Use code view to spot optimizations
Preview state transitions in the browser regularly
Remember that changes only apply to a single state
