I'm unsure where to place the commas:
[some argument], and, therefore, [blah blah].
or is it
[some argument] and, therefore, [blah blah].
or is it
[some argument], and therefore, [blah blah].
or none of the above?

It’s difficult to say for certain without seeing an actual sentence. However, a comma is frequently used before and when it joins two clauses, (see?) and, since therefore is a weak interruption it, too, (like too, see?) may be set off by a pair of commas. That background suggests that the first solution might be the most appropriate one.
