1. How can I move the ossia stave up slightly so that it isn't 
contacting the beam of the 32nd notes in the main stave?

2. Is it possible to put a vertical dotted/dashed line at the 
beginning of the ossia from the bottom of the main stave to the top of 
the ossia stave?
Well to answer my own question, I used a couple of hacks. (1) by putting 
a blank markup below the ossia stave, and (2) with some Postscript and 
trial and error with the values:

#(define ossialine "0.07 setlinewidth [0.85 0.25] 0 setdash -1.7 2.9 
moveto 0 -11.5 rlineto stroke")

            alignAboveContext = #"guitar"

            \override StaffSymbol #'staff-space = #(magstep -4)

        }
        {
            \key g \major
            \clef "treble_8"
            \stemUp \slurDown
            { \times 4/5 { fis32_\markup { \postscript # ossialine }( 
g_\markup { " " } fis) e( fis) } }
