I only see 800x600 in my 'resolution' list but my screen is capable of 1024x768. How can I increase it? I remember that I got the option when installing the system but I recently installed and wasn't prompted.

Try
dpkg-reconfigure xserver-xorg
I get this ouput
c-5feb70d5:~# dpkg-reconfigure xserver-xorg
Package `xserver-xorg' is not installed and no info is available.
Use dpkg --info (= dpkg-deb --info) to examine archive files,
and dpkg --contents (= dpkg-deb --contents) to list their contents.
/usr/sbin/dpkg-reconfigure: xserver-xorg is not installed
Seems like you have xfree86 instead of xorg as the X server then (my Debian has switched to xorg).
What about
dpkg-reconfigure xserver-xfree86
