The Internet Browser, iCab Mobile can save a page as an "off-line bookmark." It is available from the App Store (can't see the price, as I already have it installed and the $$ doesn't show)
And, with an app like Print to PDF (which is unfortunately unavailable just now) you can generate a PDF through the "Print" function of iCab, or Safari, I'm sure. I think Save2PDF or something similar would be the app that can do that now. (These might be jailbroken Cydia apps, though.)
Screen Captures, might indeed be the quickest, come to think of it.
