Yes to all of the above! She still lies dead but then after I left Korriban, a new dialogue option opened up with T3 where I was able to ask about a datapad that I had never received and then all of my other party members are talking like she's alive and so are the droids on the planet but like I saw her myself dead on the floor with a pool of blood. And Visas said she was dead and so did Kreia but no they're all like we should find Vash, I'm sure she's still alive and its all weird and buggy.
