I'd second the Newhaven - Dieppe ferry, but not sure about sleeping in the children's soft play area! They also have an early morning ferry which gets into Dieppe around 2pm.
The Greenway towards Paris is around 100km on an old railway track, so traffic free and a really lovely ride. It drops you out into some lovely country lanes, so you can skirt Rouen and head back towards Caen to get some coastal action.
