MTG Salvation

I have Mindlock Orb, Psychogenic Probe, and Maralen of the Mornsong all in play at the same time.

Would each player not take 5 damage? 2 from the Probe and 3 from the Mornsong. As I see it the morsong says:
Players can't draw cards.
At the beginning of each player's draw step that player loses 3 life,
search for a card and put it into his had
shuffle his library

Since you have to do as much as possible and libraries can't be searched wouldn't it say:
Players can't draw cards
At the beginning of each player's draw step that player loses 3 life and shuffles his library

Sorry I think I just posted to the wrong area again. Can this be moved to the ruling area?

You're basically right. They're taking damage from the Probe, rather than losing life, but otherwise these cards will have the effect you describe.
