IB, the Oregon stretch is kinda slow going. Don't plan on doing 60 mph. Manzanita Beach on the north Oregon coast is a nice long pretty beach for walking. Little towns all along the coast to look around in. You can buy a kite at a local shop and fly on the beach which is a blast if you enjoy that sort of thing.
If you have a smart phone you can Google gunshops in the upcoming towns before you get there and hopefully hit them all on your way by! I've picked up some sweet rifles along the coast. Local economies are depressed so retailers appreciate out of area cash.
The redwoods are a very few miles inland right near the California/Oregon border and you really need to see them to believe them. I'd take 2-3 days minimum to go thru Oregon, can't speak to the rest.
We are about 100 miles inland but my wife and I would love to meet you on the coast on your way thru if you'd like to do lunch or whatever. Don't hesitate to give a shout.
