EZID will create a unique string for you. If you choose to create a custom remainder, best practice is to not include information that is subject to change, which impairs persistence. Please check Custom Remainder Rules for permitted characters.
DataCite
Required for DOIs. More here: http://schema.datacite.org
Dublin Core

ERC
Electronic Resource Citation, default for ARKs. More here: http://dublincore.org/groups/kernel/spec/
A public status means the identifier is viewable by anyone. The reserved status means it is viewable only by owners, so "reserved" is a great way to save a DOI or ARK for use later. Reserved IDs can be deleted.
A public status means the identifier is viewable by anyone. An identifier with unavailable status is also public, but only insofar as it redirects to an EZID-provided "tombstone" page, displaying the identifier's citation metadata and the reason for the object's unavailability.
Your choice pertains to making the metadata available for harvesting and/or indexing. Choosing "Yes" does not guarantee that the metadata will be harvested or indexed, but choosing "No" removes the possibility.
About Proxy Users
An EZID user account may designate another EZID user account as a proxy user of the first account's identifiers. This gives the second EZID user account the right to manage and edit detailed information about an identifier.
No wildcards allowed (i.e. asterisks, question marks)

ID Create Date
Date when identifier was created. Format: YYYYY-MM-DD
ID Update Date

A value indicating the visibility of the identifier and its referenced object
Allows harvesting?
A value indicating that the metadata is or is not available for harvesting and/or indexing
