  At the start, the advice was to configure individual /64 for 
loopbacks, however latterly its assign a /64 for loopbacks and configure 
/128 instead.

  Stick with a /48 for sites/customers.

  The best advice is to use nibble boundaries  (see: 
https://www.ripe.net/manage-ips-and-asns/ipv6/ipv6-subnetting-card) 
hence /52 /56 /60

  I also recommend watching this (Tom Coffeen from Infoblox at UKNOF35 
which covers this exact subject):

  Its worth a watch and covers the basics
