Well to white balance you can meter (measure) off any mid tone.. (although it's not ideal, i did mean if you were in a fix and there was no mid grey to measure off)
And white balance is still very important in RAW as getting it right in camera means less post processing and in mixed (incandescent and tungsten or flash/sunlight mixed together) lighting conditions it is pretty much the the only way to get it spot on, doing it after is very difficult to avoid casts in these situatons...also changing white balance radically in RAW if you have shot at a medium ISO or higher can result in more noise and dynamic range reduction in some situations...so it is still better to meter from a 18% kodak grey card in situ and get it right from the start
