Archydro preprocessing for contours only

Greetings everyone,
I'm extracting contours from a 20m DEM for use in a topographic map.
I used the 'Level DEM' and 'DEM Reconditioning' tools in Archydro on d DEM.
I then took the 'Agree DEM' to Globalmapper for contour extraction.
I was really impressed with the improved conformity of the contours with the streams and lakes from d resulting 'AgreeDEM'.
Questions:
Since I'm only interested in generating contours and not watersheds:
1) Are other functions like the Assign/Burn stream slope, flow direction, accumulation, depression evaluation. etc necessary
2) Will d elimination of sinks on d DEM have any profound effect on the resultant contours.

Ur responses are welcome.
