Answering in reverse order:
____________________

Barlines belong under Staff and have two specially named thicknesses.
Try
     \override Staff.BarLine #'hair-thickness = #1
____________________

These offsets are normally set up by \voiceOne, \voiceTwo etc. 
which you have done explicitly (inside ChoirStaff).
 
But the  <<  {...}  //  {...}  >> construction implicitly
sets up its own \voiceOne, \voiceTwo etc. 
You can see the effect of this by swapping the order of these {...}

I don't know enough about it, but my feeling is that markup is unsuitable for 
this. 
Search LSR for "rhythmMark" to see how complicated it can get. 

You are using separate markups to get the horizontal alignment. 
But to get a single vertical alignment you should have just one markup. 

I would suggest setting up an auxiliary staff having everything but the notes 
blanked out. 
Search LSR for "Engravers one-by-one".
Also, with this approach no local <<  {...}  //  {...}  >> construction is 
needed.
