remiss:
You will need to load the arduino isp, then hook up the breadboard and then burn bootloader. Then you can replace the chip if you want to and upload sketches..Any reason you want to replace the chip?
I'm using them for a another project. I need to load an arduino sketch on all 10.
Once I have the boot loader on I then can just put the chip in my uno and program it from there can I not?
Also does it matter that it's an Atmega328-PU? The one that's in my uno is an Atmega328P-PU
