There are a few things that will kill these chips.

Heat
voltage: Keep it between 5V and 15V
Current: Don't plug it straight into a wall
Polarity: Make sure the + and - are correct

The resistor and capacitor should not affect the chip at all. They are just used for timing.

And you can stick the LED's on either side of the chip. Set one up on a bread board, and just play around with it. If the pins don't work, flip the polarity of the LED. If it still doesn't work, well then, don't use those pins. It won't fry the LED.
