I currently work at SCH, as far as I know they do not offer nursing residencies. I was hired on as a new grad right after graduation. If you really want to work for them just look for jobs that say new grad RN's welcome to apply. As for your resume/application what I remember is that you will need good letters of recommendation. You can absolutely live in Seattle without a car. The bus system works well and SCH has a good shuttle system too.
