Cycling through movie instances?

Hi all,

I am currently working a flash map which feature over 600 plots, which i need to be able to cycle through and control via actionscripting.

The position of the movieclips will generally not move and remain in position to its relevent parent movieclip, ~At best i wish to assign properties to each movie name, or cycle trhough each instance name.
(e.g a loop that adds a incremental number to the instance name and lets me change colour/alpha of the object)

I have a good understanding of actionscript 2.0 and have searched the web and books for the correct direction. Just wondered if you guys could point me in the right direction?

Do I do this with OOP, i.e assigning objects to each plot point:

Plot 120: Property type: Escher Size: 3 bedroom etc

Or with arrays? or a more simpler way?

Desperate for some guidence on this guys.
