I've done the drive a couple of years ago, as far as Pego where I live.
As far as route's concerned, you need to drive along the coast to Bilbao, then cut inland past Logroño to Zaragoza, then down to Valencia past Teruel, and back home down the AP7. I advise taking the N road at Tudela to Zaragoza instead of the motorway to save paying tolls. There are no tolls after Zaragoza. Bear in mind these roads cross some desolate, high country. Keep an eye on weather reports in winter.
In terms of hotel stops, it depends on time of day you are landing. I think I arrived at Santander early evening, in very bad weather, so was glad I'd booked an overnighter at Hotelandgo, Miranda de Ebro, a couple of hours drive from the port. If you can go a bit further, I can also recommend Bed4U hotel at Tudela, which I've used for other trips.
Good luck!
