First...the Oregon Coastline is EPIC!!! This is actually on the top 10 list of places to see in one's life, (acording to the Travel Channel I believe)
If possible, a stop at Crater Lake is an absolute if you've never seen it...

I'd very highly reccommend Silver Falls State Park...

It's about a 10 mile hike to do the whole loop, and we camped there yet again last month. (probably our 15th time there, and my wife's absolute favorite place to go & camp) There are 11 HUGE waterfalls (many of which the trail goes behind). They have a wonderful campground right there....but you definately need to make camping reservations, so be sure to do this!!) This place is PHOENOMINAL!!!
Do you like hiking??? If so, you could do a day or two hiking and backpacking on the Pacific Crest Trail...

which skirts right along Crater Lake, and comes very close to Silver Falls SP.
Into outdoor concerts???...https://www.brittfest.org/performances
a killer place to watch big names perform under the stars.
There is so much to see in the PNW, that it'd be hard to figure out what to see, and what's gonna hafta wait until your next trip out here!!!
