74LVC595.
+1  I suggested 595 several days ago...  comes in different logic families.

Just string a few in series, or if you are in a hurry for faster updates you can use them in parallel with separate enable lines. Series is probably fast enough for most applications.

Looks OK. Remember to add decoupling caps to all of the shift register power pins. And remember: the bits you shift in first end up at the last chip in the chain.
