The expression "a thing or two" seems to have a meaning of "information" and "knowledge," but can I translate the meaning literally as "a thing or two (things)" or "one or two"?

The expression "a thing or two" does refer to "information" in this case. Normally, it does not literally mean one or two "things". Since knowledge is an uncountable noun, "a thing or two" refers to some knowledge or information in general.
