If you want to populate the author, just paste it directly into the preview grid on the right side of that first Step 1 of the wizard. All columns are editable there, so you can do any "input" cleanup you require before moving to Step 2.
I had no issues with populating the published date with just that 1969 - calibre created the empty book with a date of 1 Jan 1969 with no extra help.
The year showed in the column during the test, but not after import.
Ah! I did not realize I could edit fields.
