Your pedal axles appear to be Gran Sport (no rifling on the axle), but they interchange with Record and use the same number of balls: 48, but it can't hurt to have a couple extras.
I did not remove the inner dust cap but if needed, it takes a blind bore bearing removal tool and it is pricey. Try to clean the pedal shell without removing the inner cap. A small brush like a tooth brush will get into the space and clean it pretty well. A petroleum solvent like mineral spirits usually works well If you don't have another solution for cleaning.
Agree, do not mess with the inboard dustcap unless you have the proper tool. It's too easy to damage it when you try to remove it. A toothbrush or Q-Tip with OMS works well to clean the inboard race with the dustcap in place. A rag and/or compressed air to remove any solvent or grease remaining.
