Yes, adhere to the substrate first. Apply the finished floor covering manufacturer's recommended pressure sensitive adhesive and allow to flash until tacky. Use a 75 or 100 lb three section roller to secure the underlayment to the substrate prior to installation of the finished flooring.
SoundStep can not be installed under hydronic radiant heat board as it was designed to be installed on top.
I used it to install over 600 sf of nail down 3/4 in solid wood.
The difference is the material they are made out of primarily. QuietWalk is a recycled fiber mix that does offer a bit more sound control in lab situations and in reviews, insulating value, and moisture emissions allowance from concrete at 5lbs per 1000sf per day. Because of QuietWalk's dense construction, it hold up longer over time and not crush as easily vs foam based underlayments. Crosslink foams like Soundstep do perform well, but if you look at the features side by side...the better attributes do favor QuietWalk.
Please note that I am a carpenter, rather than a sound engineer That said, due to the closed cell nature of this product I do not believe that this would be my product of choice. The sound dampening effect is more intended to reduce squeaking caused by floating floor systems rubbing against the subfloor. To my experience the better choice for your application might be an open cell "egg crate" style foam or one of the sound dampening products designed for this use.

Yes
Adding a premium foam underlayment offers other benefits compared to moisture barrier such as compression resistance, sound absorption and thermal value to keep your floors warm. You will have to contact the flooring manufacture to see if it serves as a moisture barrier.
Yes, underneath of course. Not sure why the other answer assumed you're putting underlayment on top of a floating vinyl floor :)
