I can help with number 8, as I make a fair bit of music myself.

FL Studio is arguably the easiest to use out of the three, but the work flow isnt very intuitive and it completely relies on looping. Almost. FL Studio is kind of an all rounder but I wouldnt recommend it for instrument based production.
Reason is an awkward one, it isnt compatible with many other softwares and it doesnt export in certain sound files. Its designed to be used as a tool to start music from scratch, rather than using various other sources to help the production process. Reason is best for computerized music (Techno, Electronic, Dubstep)
Cubase is perhaps the best choice for instrument based production and has the best workflow out of all three. However, the interface is quite cluttered and its not always easy to see what your doing. Computerized production is also more difficult in Cubase because its not designed to handle lots and lots of MIDI data.

I've used all three and I liked Cubase the most.
My personal recommendation would be to get Presonus Studio One. Its like a Windows compatible version of Logic in many ways, but still incorporates the automation and looping functions you need for computerized music. Plus it comes with a load of VSTs to help you out.
