I think these questions are addressed in the "Dubious Stragetegy Guide", but basically the "attack" command is pretty much identical to to "move" in sequential games and is only really used in simultaneous games. In simultaneous games, all ships move at once, so the "attack" order is used to have your ship or fleet SEEK the enemy ship or fleet, not just move to a location.

"Sweep Mines" is of lesser use, but can be used if you are in a sector and just had a battle with the enemy and he dropped mines during combat. Using this command would sweep the mines in the sector without having you move to another sector then move back.

Hope this helps.
