Answer 1

1. Hunk #1 succeeded at 508 (offset 1 line)

The message you see means the file was successfully patched, offset 1 line means Some lines had only spaces but they got trimmed to empty lines, so the patch file applied correctly, but with offset factors warnings display.

2. lib/Varien/File/Uploader.php. Please compare with your version core file. Any space or changes in your files. if there update file and apply patch.

Thanks
