If the original version had a price you should be fine interms of price, the only price i set for my app was with the original version so you're good to go. Everything from here on in is an upgrade price.
Yeah change the version in the XML to a version that hasn't be signed, i believe you wanted to use (1.2) then do the double sign process no need for any new keys everything is good with that just the command line stuff.
Good luck and just send me a message if you need any help!
