Using SDSS data / finding a catalog
From what I can see, you already found what you were looking for. The table you linked is the description of the data available in the Catalog Archive Server (CAS) database. All you have to do now is use those table names (it seems that masses are on different tables, here and here) and then search whatever you want. If you do not have constraints, you could just search by sky regions, but I would recommend you to use the SQL queries as you can manually select columns an even join tables. Just to give you a quick example:
SELECT TOP 10
   p.specObjID, p.ra, p.dec, p.z, p.bpt, p.Flux_NeV_3425
FROM emissionLinesPort as p
WHERE 
   p.z BETWEEN 0 AND 2

You will get a table with the first 10 results that have a redshift between 0 an 2. Columns will be ID, right ascension, declination, redshift, classification and flux of [NeV] 3425 (everything described in the table you linked). Note that for masses you would have to change the table by editing emissionLinesPort and using stellarMassStarFormingPort or stellarMassPassivePort instead (as well as change the columns accordingly).
