For starters just pick one of those. You can start with the default (new)
code.

You can start by just assuming that ap->a_onehit is TRUE. If you do need
that in the rendering phase, you can pass it as a parameter to the
respective kernels in
https://svn.code.sf.net/p/brlcad/code/brlcad/trunk/src/librt/primitives/primitive_util.c:clt_frame()
which is called in
https://svn.code.sf.net/p/brlcad/code/brlcad/trunk/src/rt/do.c:clt_run().
As for rp->r_min, and rp->r_max IIRC those are the rmin,rmax bounds
determined in rt_in_rpp() in rt.cl. You can get their values from
bounds->p_min,bounds->p_max in rt.cl:shootray(). You'll have to pass those
to the shot() function and then the respective METABALL shot function.
