Games from the original Xbox can only be used on the 360 using the programming updates from Xbox Live. I believe these updates are stored right into the 360s internal system. The HDD will just allow you to DL games and videos from Xbox Live Marketplace and hold music and save games and such.
And for Live, simply read these

If you have High Speed and your console is already plugged into the router then you can skip right to Step 3. Although, if you have time you may want to read it all.
