I`m thinking that Gabe is the specimen, question is, how to release her, i`ve taken the dogbowl back to the thinktank and uploaded her bark, when i try and complete the quest the direction arrow points me to the door....am i missing something here?

You have to go get the key for the x-8 kennels in x-13 (?) And there will be a terminal in there that says release unusual specimens. It's not Gabe.

I hated that quest so much, i died like 5 times ><

I about died when someone exploded after I killed it.

I hated having to run the course with the nightstalkers

What was the point of that, anyways?
