Data Release 7 (DR7) is the final data release for SDSS-II. DR7 contains several datasets: BestDR7, TargDR7, SegueTargDR7, Stripe82 and Runs. Details of each dataset can be found on the DR7 Data Products Web page, including links to the CAS sites corresponding to each dataset. You should also look at the SDSS Legacy Survey page for information about data in the DR7 legacy survey. The SEGUE imaging data is available in a separate database in the CAS, SegueDR6, whereas the SEGUE spectra are part of the main database, BestDR6. You can browse SEGUE imaging data on the SEGUE SkyServer site. The SEGUE spectra are in the special SEGUE plates in the BestDR6 database.
