iOS iPhone SDK custom installation, what do I need?

[9007938]

FYI, I will be developing iPhone Apps only and don't want to install unnecessary things.

Options are:

Developer Tools Essentials (Required.)
iPhone SDK (Obviously need.)
System Tools (Do I need? It's checked by default.)
UNIX Development Support (Do I need? It's checked by default.)
Mac OS X 10.3.9 Support (Know I don't need, not developing anything for OS X, particularly not an old version.)
WebObjects (Do I need? It's NOT checked by default.)

Thanks.

I would do the first four. The last two are unnecessary.
