The speed reduction is to try to prevent problems with the burning. My
burner claims to be able to do 24 speed but it just can't write a 2 meg
file at that speed.

-pad does something nice or so the Knoppix FAQ suggests.
If I understand it correctly it matches each block of the iso file with
a corresponding block of the cd and fills any empty space with empty
space rather than writing the next block of data back to back in a
contigious fashion :)
My understanding is that an advantage arises when you try to write a
boot sector and it foobars. It keeps the boot data only to the boot
block.
This as they say is my understanding, however someone more than likely
has a better definition and more will have more technical definitions.
The olde one YMMV applies in buckets particularly bit buckets :-)]
