Sure, all are very reasonable questions. Rotation sites are good and in my opinion getting better as they settle into their hospitals, not sure about compnw but some do schools seem to struggle retaining consistent hospital sites, ours seem to be stable. I also have appreciated the benefit of most of our places having residents around but not to the point of eliminating our experiences. I think the benefits of community teaching hospitals is more autonomy and hands on experience so the balance is good in my opinion.
As far as boards and match rates... I can't tell you specifics about boards but you could contact the school. First classes boards were above comlex national averages on both levels 1/2 and usmle step 1 was 100% pass so I'd say that's very solid evidence you'd have what you need to succeed for Boards. Our matches are coming up so stay tuned for those. Military match happened in December, everyone matched, one even into derm I believe.
