Ugh, I always do this. Solved my own problem fairly shortly after posting. But thanks for your reply Pazil!

Apparently my problem was in try to calculate the x and y positions using the same functions. I'm guessing I only have to deal with the z-axis once, and my old code dealt with it twice, causing the errors.

So my new code has separate function for finding the x and y positions. Now, I have have no idea how flawed this attempt may or may not be, but here's the code form my latest version for those interested:

var magic = 180/Math.PI;
function getA(x1,y1,z1,x2,y2,z2) {
    var d = Math.sqrt((x2-x1)*(x2-x1)+(z2-z1)*(z2-z1));
    var yd = y2-y1;
    var r = Math.atan2(yd,d)*magic;
    return r;
}

function getAX(x1,z1,x2,z2) {
    var zd = z2-z1;
    var xd = x2-x1;
    var r = Math.atan2(xd,zd)*magic;
    return r;
}

p0 = [-50,-50,-50];
p1 = [-50,50,-50];
p2 = [-50,-50,50];
p3 = [-50,50,50];
p4 = [50,-50,-50];
p5 = [50,50,-50];
p6 = [50,-50,50];
p7 = [50,50,50];
p8 = [0,0,0];

var x = 50;
var y = 0;
var z = -50;

var xa = 0;
var ya = 0;

for (var n=0; _root["p"+n]; n++) {
    _root["p"+n][3] = "0x"+random(10)+random(10)+random(10)+random(10)+random(10)+random(10);
}

onEnterFrame = function() {
    removeMovieClip(s);
    createEmptyMovieClip("s",1);
    
    z = _ymouse-180;
    x = _xmouse-180;
    
    if (Key.isDown(Key.UP)) y++;
    if (Key.isDown(Key.DOWN)) y--;
    if (Key.isDown(Key.LEFT)) x++;
    if (Key.isDown(Key.RIGHT)) x--;
    
    if (xa >= 360) xa = 0;
    else if (xa < 0) xa = 359;
    for (var n=0; _root["p"+n]; n++) {
        p = _root["p"+n];
        s.attachMovie("a","a"+n,n);
        o = s["a"+n];
        
        var c = new Color(o);
        c.setRGB(p[3]);
        
        x2 = getAX(x,z,p[0],p[2])+180;
        y2 = getA(x,y,z,p[0],p[1],p[2])+180;
        
        o._x = x2;
        o._y = y2;
    }
}
