If your experience level is low, just start with a single 74hc595 and build a circuit to flash a few LEDs. (74hc595 does not have constant-current outputs so you will need to use series resistors for each led, e.g. 330R). Then move on to using a single tlc chip instead (with tlc you will not need the series resistors). You should be able to find tutorials on both these chips (separately) on the net.
