I totally agree with Stan, the resistor assortment is very useful if you don't have a lot of parts around. I actually bought the surface mount equivalent kit in several sizes for when I'm working on a new design and just need a specific resistor value. I still have a huge bag of thru-hole resistors from years ago, so I have those covered.
I only use the ceramic LED's when nothing else will fit, many times I can use a 2mm post LED for those applications. I keep plenty of these on hand in various colors, as well as bi-color and blinking styles.
