for the internet your dns is prolly not setup. in /etc/resolv.conf you need a line like:
except with the ip for the dns server, winipcfg should show it.
for the resolution try hitting control-alt-keypad+
if that works then edit /etc/XF86Config and change the line that says Modes "640x480" "800x600" to Modes "800x600" "640x480" and the default depth to whatever you want
