"Rabadon's Deathcap because instead of 50 AD your shield will be giving 80. I measured, even if you have Mejai fully stacked, it will give you less AP."

I don't think anyone has ever said that Mejai's is better unless it's your only AP item. Rabadon's is the premier item for casters, much like Infinity Edge is the premier item for ADCs. Of course they're better than Mejai's and Sword of the Occult. They're also well over twice as expensive, which is why the snowball items are attractive.

As far as suggestions, Janna has pretty low base and scaling numbers on her abilities. I wouldn't bother with too much AP or mPen on her. The biggest change I'd make is removing the Ardent Censer and getting a Sightstone again. The only champions I'd consider Ardent Censer on are Lux and Alistar, since they have AoE abilities for team instagibbing of towers. Everything else was pretty much covered by other replies.
