I would suggest choosing your "lifestyle" based upon what most of your day consists of. Then, add your specific exercises/activities (or as close as possible). Many of us also add in 8 hours of sleep as we find the calorie burn to bit a bit optimistic when compared with reality.
PS From what I understand, the only way to boost your basal metabolism is to increase your muscle mass. And, that takes quite a while unless your on some performance enhancer (not that it can't be done, of course).
