the best solvent to get the old ink out? What ink to refill with?

That looks like the unpressurized ballpoint. I never tried to refill mine.
Another option is making replacements. I found current ballpoint
refills and cut them down. I used a dremmel with cutoff disk. Watch for
splatters. I then stuck something in to remove 1/4" or so of the ink from
the end. Otherwise it will come out in the pen holder and make a mess.
The problem now is almost all refills use a larger diameter tip. I had to
look around some before I found the proper size. I did grind one larger
diameter one down by chucking it in a drill and grinding with the dremel.
