For setting custom white balance:
Find something neutral coloured that you can use as a target to measure white balance from. This could be a standard grey card or almost anything else that approximates the color of one (or rather its lack of color). It needs to be big enough to fill the frame with whatever lens you are using.
it’s best to avoid using a white target. The human eye is much better at judging colour cast on a grey item than it is on something that is white. Take white copy paper for instance: if you have two different brands , put a sheet of each side by side and you will find they aren't the same shade of white. You could hold the lid of a Pringle's tube in front of your lens-and set white balance-I know it sounds a bit low-tech-but it works!
White balance for general use:
White balance
Where, with film you either shot print film in daylight or with flash indoors, and with slide film, you used daylight or tungsten film, or used compensating filters with these. White balance is Digital’s version-you select a white balance based on the condition of the light you are using, so the camera’s meter allows for white to photograph as white
Auto white balance does a reasonable job most of the time, but it cannot cope in some situations-especially when subject is in deep shadow. You need to know when to use the white balance settings for all situations, and this table will help you understand: ( degrees Kelvin is a means of determining colour temperature)
Sunrise/sunset 2400-3000 Kelvin……………………Use Auto white balance
Tungsten lighting 3200-3500 Kelvin ……………………Use tungsten/Incandescent white balance
Fluorescent lighting 4000 Kelvin …………… Use fluorescent White balance
Early morning/afternoon sun 4000 Kelvin…….Use auto white balance/ --fluorescent white balance
(Magenta filter) to counter greenish cast on skin from foliage if under trees or on really green grass
Noon sun/Sun overhead…5000-6500 Kelvin…………………….use Cloudy White balance
Flash photography in daylight 5500 Kelvin ………………………Use Flash White balance
Deep shade………………….6500 Kelvin…………………………Use cloudy/shade white balance
Shade in daylight 7500 Kelvin ………………………………......Use shade white balance
Heavy overcast, very dark shade 8000 to 10000 Kelvin………Use shade white balance plus 81a-85c glass filter

The idea is to set your camera's WB according to the 'Rule of Kenny' but tweek it in your RAW converter if you need to.
You can also get one of these: http://www.adorama.com/IMQPC.html?searchinfo=white%20balance%20card&item_no=10
I just recently bought the Lastolite version. Its like a reflector. Folds up into a pouch. Mopre expensive but hopefully will last that much longer.
