Buds contain more caffeine, but at the same time they're steeped at much lower temperatures resulting in less caffeine extraction. I think in practice, it's just so hard to come up with rule of thumbs on caffeine levels.
I'm not a white tea drinker, but mostly because I don't have any. I have nothing against it, I just never think of buying any.
As far as white tea having caffeine, why wouldn't it? White tea on average has more caffeine than other teas because it is less processed. When the tea is oxidized to make it green or black or whatever, some of the caffeine is destroyed. I read the detail here
