If I buy a Magic Memory Stick and a Pandora Battery will it work with PSP slim with 5.50 custom firmware?

I have a PSP slim with custom firmware 5.50, Im having trouble getting custom firmware myself so I thought I would buy a Magic Memory Stick and Pandora Battery instead of making them myself. Will this work on my PSP or just be a waste of money?
