All the above plus Miami, Newhalem Rivers. Newhalem is a bit north, a very nice state park at the mouth of the river. You can also drive up Hwy 53/or Miami Foley Hwy (about 30 ish miles, if I remember correctly)) to N. Newhalem state hatchery. Ample parking and decent trails, you can work your way up or down the river. I have only been there in the late summer, so I don't know how fishing is this early. Newhalem can get some nice Kings/Steelhead, and has cutties throughout the sysytem. There are other pull outs to hit that are not as far of a drive from Hwy 101.
Near Rockaway is Lake Lytle, it is stocked with RB's. It has a fishing dock and some areas you can fish from shore, but a float tube woud be best.
There is a lot of fishing opportunity in the greater tillamook valley and beyond. Look at google map/check the regs. There is also a nice tackle shop in tillamook, buy a couple flies and hit them up. I got a couple tips from them many many years ago.
Good Luck, Have fun!!!
