It would depend how you're completing the sentence. On the one hand, you
would say:
"My name and address is Amanda Marx, 123 Main St., Anytown, OH 12345,"
because in that case you're treating them as a single entity, as they
would be on a mailing label, for example.
However, you would say:
"My name and address are Amanda Marx and 123 Main St., respectively,"
since in that case you're distinguishing them as two separate entities
(though the sentence would be more confusing than a simple "my name is XXX
and my address is XXX").

Interesting.
I would tend to say "My name and address are ------,"
but
"His name and address is --------" and "What is your name and address?"
["What are your name and address?" while grammatical, doesn't sound right.]
The phrase could be looked on as a collective compound (cf. bacon and eggs,
pie and ice-cream), so that I am thinking of mine being separate, and his
being one.
