For daylight I'd try around 5500/5400 kelvins and tune as required (ie magenta/green etc etc)
If there was one issue with the SLT model I have noted it's in low kelvin auto WB which is too warm, this is odd as Sony are reading directly off the sensor. Also 2500k needs a bit more range for some energy saving bulbs (I'd increase it to 2000k) Sony really need to nail this or add a "strong correction" to the menu's like other makers have (and the other makers who have..IMO do quite well here)
Metering wise it can be like most cameras, a bit over..or a bit under but seems mostly consistent so far. Needs about a stop more in lower light levels (I use CW metering here works better) It does however not have any of the gross overexposure I had on the D7k (at times over 2 stops overexposed) Like the A200 is can be a bit under if you have lots of white/light shades in the frame, I map the spot metering to the AEL button so that works quite well for me.
