Answer 1

It looks like you mixed up the farms. This is how to do it
On Consuming farm: export root and STS cert
On Publishing farm: export root cert
On Consuming farm: import publishing farm root cert
On Publishing farm: import consuming farm root and STS cert
On Publishing farm: set permissions on topology service using Consuming farm id
On Publishing farm: publish the SA
On Publishing farm: set permissions on the published SA
On Consuming farm: consume the SA
And you don't need any specific certificates - SharePoint has its own certificate store.
