Start with the strobe and output enable set to 1.
Then as you clock the chip, the value on the data pin (during the rising edge of the clock will be shifted through the outputs. You can check that by doing it slowly and having LEDs attached to the outputs.
Once you have that working, you can use the strobe input to cause all of the outputs to be set at once. This means that while it is 0, the data will still clock in as before, but you won't see it on the outputs. On the rising edge of strobe, the data is transferred from the shift register to the latch.
If required you can also use the output enable to effectively disconnect the outputs. I think it's unlikely you'll need to use this.
Note that there's no way to clear the chip. You need to clock 0's through the whole string of chips and strobe that to the outputs to achieve that. This is a relatively long and complex operation, but it's also essentially the same as setting any arbitrary output so you'll need a routine to do this in your code anyway.
