Turn off Mac when not in use?

[eneeds]

Hey guys,

I just got a brand new 13" Macbook pro and I want to keep it in the best possible condition. Something I've never been able to get a straight answer on is whether it's better to shut down the computer between uses or leave it on and closed. I've also heard conflicting things about whether or not to let the battery die--someone told me it's good to let it run out occasionally, but someone else told me if it crashes during repairs it can damage the HD. What do you guys think?

Set it to go to sleep when not in use. You don't want to start it up every single time you feel like checking your email. Its not good for the hard drive.
