What should I do if I may have placed the same order twice?

Do not assume an unintended order will be canceled automatically. If several people are arranging the purchase, check whether someone else submitted a separate order.

What should I check before agreeing to a seller's proposed resolution?

Check whether any remaining issue would need separate handling. If someone else manages the order, confirm that they understand the proposed outcome.

What should I check before accepting a suggested substitute?

Do not assume a more expensive substitute is more suitable for your use. Ask whether the original option remains available under a different arrangement.
