I'm not a fisher person, but suggest googling Newport or Depoe Bay fishing charters. Bring something for seasickness if you are prone to it.
I like Otter Rock a lot. An oldie but a goodie. I think the condos are all done differently, some are updated and some aren't. Some are fully owned and I think only a few are in a timeshare pool. I think you were lucky to trade into this. It is located within The Inn at Otter Crest.

There are usually seals on the rocks if you head right at the bottom of the beach stairs. The rocks are slippery, bring some water shoes with good traction for exploring the tide pools. The whole beach there is an Oregon Marine Preserve, meaning you cannot take shells or rocks from it or disturb the sea life in any way. The tide pools are great, lots of starfish and other sea life. We have even seen a small octopus in one of the pools.

There is short trail from the resort through the woods to the Devils Punch Bowl, a cool rock formation that can shoot water out the top when the waves are high.
http://oregonstateparks.org/index.cfm?do=parkPage.dsp_parkPage&parkId=156 (You can access it at low tide from the beach below, but be aware of the tide!) There are a couple tiny places to eat there.

Another good restaurant in Depoe Bay is Tidal Raves.
http://tidalraves.com/ Great view and very popular. If you go, try and get reservations for when it is still light out and you can see the view. There is a resident pod of whales that hang out in the area, and we have seen them from there. We also like Blackfish Cafe in Lincoln City.
http://blackfishcafe.com/ Never had a bad meal there, but no view. In summer, reservations are a must here also. And if shopping is your thing, there is an outlet mall in Lincoln City.

I have never been to Local Ocean in Newport as Tahiya suggests, but everyone raves about it, and it is on my list.
http://www.localocean.net/ I would try for a reservation here for sure, the earlier out the better. If you like beer, I suggest Rogue Brewers on the Bay.
http://www.rogue.com/ Located very close to the Oregon Coast Aquarium.
http://aquarium.org/ I second the suggestion of a visit there.
Some general Newport info.

Be aware that if it it hot inland, it it often cool, windy and overcast at the coast. Bring warm coats and sweatshirts. I will never forget a friend from California who drove her kids down to the beach for the night with shorts and bathing suits and that's about it. She had to buy warm clothes for all when they were there, as they were freezing.
Have a great trip !
