Help A Few Simple Questions

[AllThingsPure]

Have just got a Galaxy S and this is my first experience with Android. Some quick questions:

a. How do I set the host name for my phone?
b. How do I start a command line shell?

Thanks.

I believe both your questions regard Linux tweaking ?

I saw command shell software in android market as free download if my memory serves me right. Hope this helps !
