Have your second finger like barring the 2low strings on the 8th fret. So your first finger can easily get to the 7th fret.

The 5th fret in there will require you to temporarily take your 2nd finger off the 8th fret then you just lay it back on. It shouldn't be too hard if played like that. Good luck

whatever you feel is the most comfortable and hte most convenient...

I would probably use my middle finger on the 8th fret D string, third for the 8th fret A, and index for 5th fret. the rest should be fairly simple.

You must never double the leading tone ever. Failure to comply will result in a fugue related death.

I would wrap my thumb over the top to fret the bass note, leaving the rest of my fingers for the rest of the notes.
