When I did my first full detail it took me forever. Good thing I had a whole weekend to dedicate to it. I spent about 3-4 hours Friday after work, then maybe about 5 hours each Saturday and Sunday. In all, it seemed like it took forever, but the results I got were great! What I need to get now are some better lights, my LED flashlight wasn't quite cutting it to see how I was improving the swirls. Like you, I left some behind, but the overall improvement was awesome and I was happy.
On the topic of rock chips, there's not much you can do. Dr. Colorchip works pretty well (it's a touch up paint), but it won't be perfect. The only way to have it 100% like new is a full respray, but then we're talking $$. Plus, if you do a respray, you should put a clear bra on it or you'll be respraying again soon.
