For me if I leave them camera alined, not view-plain alined they

the code for facing the camera is wrong. It seems it made them face
something in-front of the camera.
This is the best screen shot I have of the original effect with
camera facing sparks:

Shot in the dark here: did you apply a scale other than 1.0 to the
trimesh? If so, then that could be causing your particles to orient
themselves prematurely (at least, that's what it looks like to me in
your screenshot). There's a note in the TrimeshParticles class which
describes the problem.
One last issue. As I said before the particles look bad with non-
black fog. I decided that I like non-black fog so I was wondering
if there is anything I can do to fix this issue. Maybe there is a
way to turn object fog off. There is a Quesa Wrappers demo that
does it, but I don't really want to use the Quesa Wrappers for
everything.
Frank's Quesa Wrappers is certainly a good starting point. Zombies
uses it to remove the specular highlight problem you described, but
what I did in there won't work for trimesh particles. I'm still
trying to figure out how to use the Wrappers with RB's Trimesh class,
as I too would love to see the fog vs. particles problem go away.
