Answer 1

"But if the array was being heavily manipulated then a single dimension array would be more efficient than a multi dimension array."

I did some profiling of exactly this last summer and was surprised to see no significant difference in performance between a 2D and 1D array.

I didn't test the performance of a jagged array.
