Duplication and swf as site

Hi folks, I only have several weeks experience with flsah so far but have built my site using it and it’s about 4.5mb. Two questions,.
1 do visitors have to download 4.5mb before seeing anything or does the swf load progressively.
2 a bit more complicated.
duplicating

I’m trying to make ‘star’ duplicate randomly from frame 0 to frame 75. VERY new to AS and studied a few tuts and found and adapted the following
dupMovie = function () {
for (i=0; i<2000; i++) {
star.duplicateMovieClip(“star”+i, i, {_x:Math.random()*900, _y:Math.random()*900, _alpha:Math.random()*50});
with (eval(“star”+i)) {
_xscale = _yscale=Math.random()*100;
}
}
};
dupMovie();
This creates a large number of stars instantly, but not progressively over 75 frames so I’m starting to understand what to ask for and how to ask it. Perhaps someone could help me along a bit. Next thing I need is to tell this script to execute over 75 frames. If someone could add to this and post it i could examine it and perhaps get on a bit further. Any takers
