Ebon may or may not actually black mail Shiro. At this point he is looking for Sapphire's daggers with the intent on using them for his own gain, which may involve black mailing Shiro. Or just calling finders-keepers. 

And to me telepathy is much like hearing someone talk: All you have to do is listen. You can whisper to try to hide it, but that implies you know someone is trying to listen. Most people aren't aware of telepaths since they don't go around making it obvious someone is listening in on their thoughts. And as long as Ebon doesn't actually try to speak back, most people wouldn't notice he's listening in unless they actually notice him.

It may be obvious since he has to look at them, but would you really think that everyone that looks at you is reading your mind? Ebon glares at people all the time anyways.

She'll kick his ass if he tries to keep them. Hell her team might not be united on much but I can't imagine that they say no to a collective ass beating to retrieve Sapphire's weapons.

With regards to the telepathy that entirely depends on the type of telepathy present in the canon of the story. If thoughts are generally external and you are doing a passive scan of what everyone's thinking at the time they might not notice but if you have to do an indepth search they're going to be able to feel your presence. That includes things like... sifting through someone's memories.
