If you have mixed lighting you will never be able to get the white balance correct.
Just as an illustration (for anyone who might learn from my mistakes) to the mixed lighting sources and WB here is an example of a photo with light sources of two different temps - one of daylight (~5500K) and the other from household lights (~2500-3000K). The little girl's (my daughter) face is lit with more yellow household light, while the back and legs are lit from sunlight through a big sliding glass door. It was kind of an "ah-ha!" moment for me while I was reviewing the photos, trying to even out the WB. This was shot in jpg, edited in iphoto and is about as good as it is going to get. I'm sure in photoshop this could be better balanced, and I believe in LR4 you can adjust color temps with the selective editing brush? But, I'm ok with it how it is for what it is.
