John's point is critical. On occasion I have tried to skimp on ISO to keep noise low. When my picture turned out blurry, I realized that wasn't very smart. But noise is much worse if I underexpose. So if I have a low light situation where I am moving into high ISO, I tend to over-expose just a bit. I would also add, though, that my personal opinion is that ISO 3200 on the D7000 is very clean and I really don't find any reason to be unhappy at ISO 6400 at normal levels of viewing.
