You will also need a 9V battery and a 47 μF capacitor. Other than that, your list is correct.

35V, sorry I forgot to mention that. You are building a DDL driver right? If ye,s take a look here DIY Homemade laser diode driver
It contains all the info you will need. There is also a schematic of the driver. I hope this helps!
