Would be my starting point for tweaking.



Personally I would also boost the saturation a slight bit (1.05-1.1).

I would not apply AutoWhite since for my taste it would alter the general feel too much. 

Also I would think about adding some light grain at the end, depending on the output bit rate I choose. (if you use high bit rates, grain can help give the image a slightly more 'alive' 'feeling', but for low bit rates it will only cause problems since it's a pain to compress.



Also if you want to upscale the content to 1280 you could:

Use something like:
