LinuxQuestions.org - a few questions about SuSE9.3

welll... I am linux noob so please don't say that I am a retard....I know that already : )

ok. I installed openbox and after rebooting...instead of a normal colorful login a gray one came on. I exited into the console which was still pretty(with a background) and did"startx openbox"(this was a pure guess....) and when it went in the background was gray.
my question: how do I ether get the pretty login back or turn off the login all the way so that it would leave me in the console?
second question: is there a command for shutting down the computer? how can you reboot or shutdown from console?
and the third: in SaX2 I change the gometry of my screen(make it wider and move to the left slightly) and press save...after reboot the screen goes back to the screwd up state(slightly moved to the right) how do I make it stay?

4th...(the last) : I am trying to install PyPanel....installes the pythonx lib and the latest Imlib2 but pypane doesn't want to compile this is what it says:
