That seems strange. Can you right-click on "system" on the top panel and choose "edit menus". A window should pop up where you can scroll down to: System > Preferences on the left pane, and check off anything you want in the menu on the right pane. You should then have those items you checked when you go to: System > Preferences.
As for the sound, can you open a terminal and post the output of:
lspci | grep -i audio
lsmod | grep -i snd
These should tell us the name of the sound card. The lsmod command will tell us what driver(s) are being loaded for it.
And did you try running alsamixer
from the terminal and making sure everything was unmuted, and volume levels turned up?
