case study for your reference: using 1d, under flourescent lighting at home, i take the same pix twice under different WB setting and load them onto computer, view via a calibrated CRT monitor, and somehow personally find that AWB is more "accurate" than flourescent WB (less greenish) . and under indoor s orangy lighting, AWB will retain the orangy look, but tungsten WB will make it look rather bluish. but usually i simply use AWB and when it comes to post processing, i wil just adjust the colour temp to warmer or cooler, depending on how i want the final pix to look like
white card is to place it in the lighting for that shot, take a shot of it, then use its information to dail it in as the referece point of the camera's custom WB

If you want an accurate white balance, you should use a grey card and do a white balance preset every time before you start taking pictures. See page 52 of the manual.

I am using the D70 as well. I have been playing around with this camera ever since I bought it 3 weeks ago. On White Balance, as long as I am taking pictures on these conditions, I will always use these settings:
Under dim candle light type.
E.g.: Shopping Centres, Restaurants, Light bulbs, etc.
Under Warm daylight florescent lighting.
E.g.: Office, house, classrooms, etc.
Under direct sunlight.
E.g.: No need to explain much on this...
When using flash photography.
E.g.: No need to explain on this except that D70 has a weak built-in speedlight. You may want to consider setting your camera on this when using flash photography -- Flash: -1.0, Exposure: +1.0. This will create a bright enough subject with a good blend in the background.
In the day without direct sunlight.
E.g.: No need to explain on this...
Under anything in the day without any sun.
E.g.: House, Room, Under tree.
This will give a warm feeling to your pictures which most of the times, look very nice, depending on what you are shooting at.

Aiyah, shoot RAW and solve all your problems... I shoot RAW and leave it at AWB until I post-process... less things to worry about...

but oso more post production work to do. I tink it is more satisfying when u are able to take a picture that is so good that there's no need to do post production.

i jus had a photo shoot for a conference using D70. Apparently the lightin in the ballroom was so orangy tt even when i put in tungsten +3 or -3 there is no effect. had to use the filter tt SB-800 provides n the pic turn out so much better...
can't remember if i did try AWB, it might have worked...

if u are shooting in a studio, i guess a grey card will work wonders for u in terms of WB....
due to consistant lighting
if u are shooting on location instead. then i will say tt its useless..... u cant possibly grey card for every shot u take...
juz set it to cloudy lo hehe..
