Here is a link to the brakes. I put it for a 1994 Ram but it should be the same for yours too.

Front Brakes Part Number: A158-2
Rear Disc KIT: A158
I don't know how much of an improvement they are because I don't have them installed yet. But I know that the stock brakes on these Rams suck so I know it can only get better!
I ordered mine from truckperformance.com
Since your going with a 22/24 combo you at least need the disc in the back.
