Display and internet

So i successfully installed leopard 10.5.2 using the new zephron iso on my amd machine. I have two problems.
I have an ati radeon hd 2400 pro. I am only able to get one resolution under the display settings. I have a 1920x1200 res for my monitor so it looks bad. I checked the box for the ati drivers in the install. How do i get the right resolution for my computer? Do i need some more drivers? where do i get them? thanks again zephron!

When i was setting up the installer it asked me for internet info. i checked"this computer does not connect to the internet". i was planning on setting it up later. when i go to change the internet settings it says there is no ethernet adapter. i made sure i checked the nforce lan driver in the installer. Anyone know how i can get internet to work? thanks
