1. How to I specify the “id” column `users`.`id`? When I put ‘join_self_as’ => ‘id’ DataMapper still appends _id so it becomes id_id and putting ‘join_self_as’ => ‘’ results in _id

It doesn't matter. It's a one-to-many relation, so Datamapper knowns which table has the FK, and therefore which field to use. The other side is always 'tablename.id', this is hardcoded.

2. Can I name the $has_many index & “class” index whatever I want (and then use the same name to reference it in other models)?

The index, yes, you can name that whatever you want. You can even create multiple entries all pointing at the same other model. You can NOT name 'class' whatever you want, it has to be the name of the model class. Otherwise Datamapper doesn't know which model to load if you reference a relationship (i.e. the index).
