"Vent" just calls out that there is a vent on the top of the cap, which
it obvious without the label. It's the scoring in the metal, which
allows the top of the cap to break open in a controlled way if the
pressure inside gets too high. Without the vent, a failing cap holds
the pressure in until it explodes like a firecracker.
The other label is actually 105℃, meaning that it's rated for a certain
number of hours of use at 105℃. That means it's probably a fairly high
quality cap. If you have to replace this cap, you'd want to match that
temperature rating as well as the capacitance and voltage rating.
You'll probably find that *all* of the caps are 105℃ rated, so they'll
have that marking on them somewhere.
(You think things are complicated already? Wait until you start
shopping for caps!)

Do you mean the chokes, which have yellow cores and red and orange
Or perhaps the dark gray cored inductors, with red wire?
Or do you mean the pink resistors(?) near the board edge?

Yes. You should have blown the dust out before taking the pics. It
needs to be blown out regardless.

It doesn't look like it to me.
