Until anyone chimes in about encryption support, i would assume that the card cannot be encrypted and usable by the phone at the same time.
Depending on the phone, the only thing between someone and the card's data would be whatever physical measures it takes to retrieve the card. (e.g. requiring a pin for the 720)
therefore I would store things onboard if I can and put less important stuff on the card.
I believe MS has security in mind when adding the install to SD option, but we can't know for sure until it officially drops.
If you had the PDF reader on the card (doesn't take much space though, games on the other hand...) I hope it would act normally with no difference in security since its just the app on the card, and anyone can download that.
As for the documents, its safest onboard and not on the card as of now.
