I wear the Fitnbit all the time and the only thing I manually log is my yoga class, since that is a lot of work and fitbit shows it as mainly sedentary! NO, manually logging doesn't further refine an activity such as running or walking that it tracks well, It would be less accurate in that case. it would only help with an activity it doesn't track well (like lifting weights, or yoga)
Sometimes I use the timer to show an "activity" but that is not the same as manually logging, as the info is the same whether I time it or not.
I don't believe any steps you manually log are included in the step totals, nor are they included on earndit, if you use that. (I'm sure about earndit, can anyone say if this is true at Fitbit? If you manually log a run will it use those steps int the weekly and challenge tally?) They know that people tend to over-log. Keeping it to a minimum and letting the Fitbit do the tallying is the best!
