First of all, please apply some semblance of formatting so your individual questions may be clearly viewed.
Problem 1. XF86Config(-4). First, tell us your monitor and video card's specs. You'll need these. Secondly, you can use
to alter the conf. with the debconf way. It works very well.
Problem 2. What sort of printer? Serial? USB? Model number? Did you install CUPS?
Problem 3. DVD player. How are you mounting it? How _did_ you get it to mount? What commands? What kernel are you booting with (`uname -a`) and are you using any kernel parameters? IF you aren't sure, copy these two files into your post: /etc/lilo.conf and /etc/fstab.
Problem 4. apt-get install menu. man menu. IT works wonderfully.
As I mentioned your post was a chore to read. Clean up your follow-ups and we can help you help yourself much, much quicker.
