Oh you don't take your shots in manual? As far as white balance goes I use auto but all my shots are taken in M mode, there is so much you can do with the variation of settings.
I don't bother with light meters though, most dslr have good built-in TTL "light meters" nowadays.
I rarely shoot in manual. I set the exposure bias and the ISO and that's about it. Shooting RAW means I can change stuff like white balance later so I leave that on auto too.
I only use manual if I'm doing night photography or long exposures and even then I just use shutter priority and set ISO and shutter speed.
