If you have a Plextor Premium then use Plextools which came with the drive and Rip the Tracks you want to Harddisc. Then burn these with Plextools to CD-R. You can also use EAC, but since you are a lucky owner of a Premium I would definately use Plextools. You could also try and use Gigarec <1 for better quality. Also dont forget to use high quality Media like Taiyo Yuden or any other CD-R brand which state Made In Japan. Any MIJ brand CD-R is of good quality.
