I would print out a copy of this:

The TTL ICs will have a half moon shape on the top of the ICs, just like
in the pictures.
The capacitors can be installed eitehr way, as can the resitors. For
the LED, one leg of the LED is longer than the other. That is the
Anode, and it should be installed in the hole to the right (the one with
the wire to pin 1 of the '244.
On the IDE connector, you'll see a little arrow down on the right lower
side. There should be a corresponding arrow on the connector. If all
else fails, the side of the connector with 3 notches in the other
platsic should go towards the ICs. Note that you will need to "pull"
one of the pins out of the connector to install it (there is not hole
for a pin in the middle of the connector (the IDE "key" hole)
