I use the traffic shaping tools provided by Linux to shape outgoing traffic on all of my servers. The linux boxes are the network gateways so it's fairly easy to do. NTP packets get classified as "real time", alongside pings, TCP ACKs and SYNs, dns queries and small ssh/telnet packets. I could send you my configuration off list if you're interested.
Shaping the downstream is harder because the traffic has already traveled across your connection. It _can_ be done on your end (I do it at work because we have to share a 3.0mbit/s connection with 50 people) but it's more effectively done on the ISP side.
