Q1: Yes. once you have all the disc loaded... be sure that for all the discs the artist and title are all the same. (not just close but the same... for example.. the beatles, are different from The Beatles, is different than beatles, the, is different from Beatles, The... etc).. same goes for the album title.. case and spelling are the most common problems. Then select "make box set" under the tools menu. You will now see just one entry with a + in front of it. The only thing that you currently have is a different artwork for each disc. If you get an error with the make box set feature... I find it is usually a problem with the fields in the general properties field part#... just blank it out.

I am not sure what you are refering to in Q3
