1. Always, always use IC sockets -- don't solder 8-pin op-amps etc. direct to the board. I'd also recommend using transistor sockets. 
2. Use a heat sink when working with certain components, e.g. 1N34 diodes, as they don't like getting too hot. 
3. Don't attempt to solder your fingers into the circuit. It hurts.

all of the above. Transistor sockets are useful, as you can often swap transistors to change how much gain/raspiness etc a fuzz pedals have, same with diodes (depending on the circuit).
