Should I use white paper to set custom wb for outdoors shooting and gray card for studio?

All you need to remember is that it's called "White" balance. A white card should be used for setting the custom WB. A gray card can be used for evaluating exposure when you're not sure if the meter can successfully handle the lighting situation on its own.
For fun, you can set WB using different color paper - gray, yellow, green, purple. You can get some interesting effects that way. But for "standard" color temperature, use a white card to set the custom WB.

Use a white piece of paper and set the camera to CW metering so it will be rendered middle gray . Actually too bright isn't good since you risk blowing out one of the channels, which will result in inaccurate white balance. Make sure the white is not overexposed, or use light grey, as long as it's not too dark and neutral. The name 'white balance' refers to the color of the light (you balance the R,G and B channels so the light appears white), not the color of the subject.
