dbPoweramp has Accurip, but no error correcting.

In EAC, be sure that under Drive Options/Extraction Methond you have Secure Mode selected. It shouldn't take a half hour to rip a disk normally, but a scratched disk, or Paranoid Mode, will increase the time.

It's OK to use EAC to compress to FLAC. It rips to WAV first and then converts that to FLAC. It can either keep the WAV file or delete it when done if you want. The extra compression step will cause the rip to take longer. Just how much longer depends on your processor speed.

I'm not sure what you are trying to do with the audio file, but your ripper wouldn't cause sync problems that altered the tempo. The only "problem" the ripper may cause, EAC or dbPoweramp, would be if the offset for the CD/DVD player was not correct, in which case you may have a few extra milliseconds of silence at the beginning of the first track.
