Hey Filip,
I've tried to answer your questions inline as best as I can:

I believe Andres answered this already. According to his example, make sure
you are using backticks (`) not single quotes (').

I do not believe it is possible to update a relationship's type after it has
been created. At least, the REST API docs do not indicate how to do this.
A quick workaround would be to delete the old relationship, then unset the
relationship's id, so that a new relationship will be created:
$relationship->delete();
$relationship->setId(null)
->setType("new_name")
->save();
You could also index $relationship this time around if you choose.

You could always assume the property exists, remove it, then recreate it:
$myIndex = new Index($client, Index::TypeNode, "indexName");
$index->remove($node, "some_key", "some_value");
$index->add($node, "some_key", "some_value");
The `remove` call will return false if the property did not exist already,
but you could ignore that.

This feature is not implemented yet. I have created an issue on github to
get it done soon.

Thanks for checking out Neo4jPHP!
