At this point you have no other choice but to be patient until the download completes and Lion reinstalls. Since you don't have a Lion disk that's the only way. After Lion reinstalls, see the instructions on how to make a backup using Time Machine. You might also want to make a bootable Lion disk or flash drive. See these instructions.
