Does 'kill the headers' mean the same as ignoring them in your code?

Define 'item' here. Is it a field, a character, is it a line?
I'm going to assume that you mean that you want to loop through the file
line by line, inserting to the database the line's fields in this order:
fields, ..., fields, fields, fields, ..., fields[n-1]
shows how the csv.reader lets you loop over csv data line by line, each
line is a list of fields. Using Python's slicing operations you can
easily rearrange the line's fields to suit your output needs.
