I need help badly....! simply site, but confused

Hello all, I am new to this forum and apologize ahead of time for probably asking super fundamental questions, but here I go;

I am pulling my hear out trying to figure out how to do a relatively simple site for my brother who wants it done with Flash MX 2004, even though it’s simple enough for html. (the 1st version was done by someone more ameteur than me in Flash MX using scenes)

A simplified site map goes as follows:

Intro
Home
Commitment
Work
Print
Portfolio links 1-40
Identity
Portfolio links 1-28
Packaging
Portfolio links 1-32
Web
Portfolio links 1-15
Multimedia
Portfolio links 1-1
Contact
Client area

Can somebody give me advice about which method to use for linking through the site which, at its deepest level is 3 levels deep (i.e., Home/Work/Print/PrintPeice01-40/). I know of a few methods but can’t figure out which is best.

-using scenes (although I have been told it’s better to stay away from scenes)
-using loadMovie and breaking each section into seperate movies which will be called to load into a container upon a behaviour (onRelease…)
-using attachMovie which I read about in the Flash MX 04 tutorial
-using movieClips and gotoAndStop/Play functions to jump to and from labeled frames in movies across various timelines (mc’s) but staying on one scene:

commitment_btn.onRelease = function (){
gotoAndStop(“commitment”);
}

If anyone can help I would be so grateful. I’ll take all the advice I can get.

A sample of the site I am working on is at:

As you might see, it’s totally buggy!

Thanks,
Jonathan
