In general, set refers to an object (“Set the materials down on the table”) and sit does not (“She sat for an hour, waiting for the bus”).
that vs. which
–“Which” is frequently used to introduce a nonrestrictive clause, a phrase that isn’t necessary or supplies additional information and is usually set off by commas.
For example: The burned CD, which she received from a friend, was of a lesser quality than the original from a music store.
–“That” is used for introducing restrictive clauses that refer to things, phrases that ARE essential to the meaning of the rest of the sentence.
For example: The CD that consists of all of the band’s top-ten singles is her favorite.
that vs. who/whom
In most cases, “who/whom” is the standard form when referring to human beings, especially in regards to an individual person. “That” is used when referring to a class, species, or type. “Which” should never be used in reference to humans.
