Following this guide on how to breadboard an arduino, I'm not sure which connections to make on Pin 9 and Pin 10 of my ATmega328P-Pu.
I'm using a 16MHz 4-pin clock with a pin-out that I'm guessing is similar to this one's layout.
The 328P-Pu is DIP packaged.
That part

needs power & gnd connnected.
Connect its output to XTAL1 (datasheet 9.8 ).
Change the clock bits to 0000 in the Low fuse byte (datasheet 9.2 and Table 28-9), and burn the bootloader to set them.

Thanks for responding.
I'm not sure which datasheet you're referring to. I've checked the one for ATMega and the data sheet I posted and there was no mention of Table 28-9.
Also, I've never worked with a crystal oscillator before. Is its only job to generate a (roughly) square pulse at the housing-specified frequency? How do I set the "clock bits"?
You're breadboard with a '328P - which datasheet did you think I was referring to? Perhaps you've seen it?
In boards.txt, change the LOW fuse byte the Uno entry to:
uno.bootloader.low_fuses=0xf0
In section 28 of the datasheet,
ATmega48A/PA/88A/PA/168A/PA/328/P
Atmel-8271I-AVR- ATmega-Datasheet_10/2014
Table 28-9. Fuse Low Byte
I don't know what you're looking at, perhaps the Summary datasheet and not the Complete datasheet?
Use a Programmer to burn the Uno bootloader onto the board.
"Is its only job to generate a (roughly) square pulse at the housing-specified frequency?"
I'm sure it will be much better than roughly - it will be a very sharp, crisp, 0-5V, 50% duty cycle square wave.
