That's odd. My Apple Dev thing (free version) looks like 
http://yomcat.geek.nz/sage/clt.PNG (that's just logging in at 
http://developer.apple.com/downloads).

This is true.

Also true.

It's one way, and the way that I use. However, you can download them directly 
from Apple, as shown in the screenshot above.

I say yes, as it seems easier. I have had issues trying to download from the 
Apple dev site.

No. Just installing XCode does not give the command line tools. You need to go 
into prefs and manually download them.

It's not very hidden, though it appears to change monthly, and it's different 
if you're on Lion or Mountain Lion.
