Nikon D3000 or Fujifilm Finepix S3200?

Hey, I am a freelance photographer and I like shooting Macro, night photography with low shutter speed and Portraits! I want to upgrade from my point and shoot camera to one of these. But I am little bit confused about which one is better Nikon or Fujifilm.My friend have the same camera Fujifilm Finepix S3200. Its great but don't know about the Nikon D3000. What's your opinion guys? Which one should I buy?

What should I use to make my videos louder?

I plan to make YouTube videos, and for one of my videos I plan to interview one of my haters on why they hate me. I plan to do it outside with a really nice set, with chairs tables and even drinks. The only thing is if I'm outdoors I know my microphone on my Nikon CoolPix Digital camera will not pick up my voice and be very buffered. Should I buy microphones and if so how would I use them and hook them up?
