Hi,
There is no quick way to add your tracks. You are at the mercy of the speed that your cd drive decides to read the tracks and add to itunes library. Not every disc reacts the same - could be very quick or very slow - depends on quality of the disc.
I suggest you use 256kbs AAC format as match tracks will be this format. Uploaded tracks will be as originally encoded except where you use kbs greater that 320kbs - itunes will convert those tracks to 256kbs.
You are again at the mercy on how quick match works. I would suggest that you choose CDs that you think you will get a better chance of a match i.e songs in itunes store. Proces can work quickly where most tracks are matched. Uploading does take time.
Be patient. Imatch works well for a lot of people but is a nightmare for others.
