Part of your problem with rigidity on the mill will be due to using a drill chuck for milling. Drill chucks are not designed for radial forces, since drills apply a largely axial force. For that reason you shouldn't use a drill chuck for milling as they don't grip very well, in addition to being prone to have higher runout. Get an ER collet chuck and set of collets off eBay and I'm pretty confident you'll see the difference. Just get a suitable size one with the right taper etc...
