Answer 1

Of the two, I'd use a temporary table for report.

A memory table holds data across user sessions & connections, so you'd have to truncate it every time to make sure you wouldn't be using data from someone else. Assuming you put in whats necessary to maintain a memory table depending on your needs, it's fine - the temp table is a little safer from a maintenance perspective.
