There is no HM Dive in either Pokemon Silver/Gold or Heartgold/SoulSilver. It is exclusive to the Hoenn games.
Yes there is an HM restriction in palpark. They do this because some of the HMs from the GBA games aren't available in platinum. For example, Dive is no longer an HM move in pokemon, and it used to be in the GBA games.
There is no move deleter in Pokemon Blue - however, there are Gameboy Genie and GameShark codes to aid in the removal of HM moves from the early games.

In all the Pokemon games, there is a Move Deleter person. Talk to him to delete moves.
