DNS server addresses should be short and easy to tape, as already
mentioned.

In many cases yes - because that makes it possible to easily move the
service to a different box.

Excel spreadsheets, HaCi.

At least as long as you use static addresses. We like static, and tend
to stay away from SLAAC. We do *not* use EUI-64 for router links. For
customer links we use /64, for backbone links we use /124 (ensures
that SLAAC can never ever be used on the link, and also that the two
ends can be numbered ending in 1 and 2 - nice and simple).
