I tried doing a similar thing for a fairly short URL. I had to add some padding on the end ("?SourceID=QR") in order to make the QR big enough to fit my changes in.

Does the QR standard allow for arbitarily high levels of error correction? (More than the "H" level.)

No, see here: http://www.denso-wave.com/qrcode/qrstandard-e.html (Denso-Wave created the QR code)
