1) Is there a general convention about addresses for DNS servers? NTP servers? dhcp servers?
There are people who do stuff like blah::53 for DNS, or blah:193:77:81:20 for a machine that has IPv4 address 193.177.81.20. For the DNS, I always recommend using a separate /64 for each one, as that way you can move them to another location without having to renumber, and make the addresses short, so a ::1 address or something, because those are the IPv6 addresses that you end up typing a lot. For all the other stuff, just use stateless autoconfig or start from ::1 when configuring things manually although there is also a little value in putting some of the IPv4 address in there. Note that 2001:db8::10.0.0.1 is a valid IPv6 address. Unfortunately when you see it copied back to you it shows up as 2001:db8::a00:1 which is less helpful.
2) Are we tending to use different IPs for each service on a device?
No, the same Internet Protocol.
Finally, what tools do people find themselves using to manage IPv6 and addressing?
Stateless autoconfig for hosts, EUI-64 addressing for routers, VLAN ID in the subnet bits. That makes life simple. Simple be good.
