I'm glad she told Clark about her time as an assassin. Maybe Clark figured it out anyway because she shot him, but I'm glad she came clean with him anyway. Is it in character for him to accept Lois in spite of the horrible things she has done? It could be. Like she told him, she was forced. Of course she could have refused to do what they demanded of her and just let them kill her. I'm glad that he accepts her anyway. However, I think it is naïve not to realize that a person is going to be changed in some way after spending two years as an assassin.
And now Lois is set on finding out who that amazing "superman" is. Clark won't tell her, because he doesn't fully trust her yet, which I sympathize with.
It will be interesting to see how this unfolds!
