Hello, I'll try to answer as many as I can.
1) Yes, but they are usually LTC or office work. Most hospitals around here are almost all RN.
2) Contact http://www.doh.wa.gov/hsqa/Professions/Nursing/forms.htm and see what they say. Your state might have reciprocity (meaning your license will transfer to washington with only a small fee)
3) Yes, lots of community colleges in the area. Some online learning process. Some hospitals also provide money for the education if you can get hired on. Very competitive in the BSN programs. Moderately to highly competitive in the ADN programs (just shop around and find their wait list)
4) Unsure maybe $15-$20+ depending on experience.
5) Seattle is expensive to live in. Most of the closely surrounding area is also expensive to live in (Bellevue, Redmond, etc). I would suggest moving to Pierce County. It is located just south of seattle and is generally less expensive to live in. The biggest city is Tacoma. From their you have St. Peters Hospital in Olympia (30 miles south), Good Sam in Puyallup (10 miles east), St Claire in Lakewood, St Joseph in Tacoma, Tacoma General, Allenmore, Auburn, Valley, St Francis, Swedish (first hill, cherry, and ballard), Madigan, the VA, Highline, Harborview, Virginia all within 30 minutes or so from Tacoma. Of course there are a whole load of LTC facilities to choose from also.
5a) Puyallup generally is rated as having good schools and a lot of new suburbs on the south end.
6) Yes. The area is very pretty, people are generally nice, a lot to do both indoors and out. It is a pretty good place to live.
Hope this helps
