to start though- first question- is Shannon theory ‘information theory’? or is it theory about communication of informaiton? As you said, it doesn’t quess where info comes from, or what it consists of, but rather describes how it is communicated? Or am I misunderstanding it a bit?

Information (Shannon, successful communications) is defined as the reduction of uncertainty (Shannon entropy) in the receiver (or molecular machine) as it goes from a before state to an after state.

It is the action of successful communication, not the message itself. The message could be Shakespeare's Hamlet, an invoice, DNA, etc. It makes no difference to the model.
