The good news: There is a AWESOME component for that: https://github.com/openzoom/sdk (look into the flex samples, there is a mapping-layers sample). The bad news: this is OLD, still working very well, but if you need do something not supported then you need deep into the code.
The horrible news: If you really need deep into the code, you need understand the basics concepts about how multi-scale mapping works: Deep zoom and about the tiles, latitude, longitude, Mercator Projector, Transverse Mercator ... understand these concepts are very important to modify/extend anything into OpenZoom. However, if I understand what you want do, the sample about mapping-layer on openZoom will fit to you basically.
