Well we all got to learn somewhere don't we? I've been there done most of that!

When you didn't have windows in the boot option thats because your 'lilo' couldn't see windows. You need to edit the lilo it can be found in "/etc/lilo" (so at console type "vi /etc/lilo") in there you need to add the lines for lilo to see windows to boot. Before editing this file though you need to know what hdaX your windows partition is on! E.G hda1=windows hda2=linux hda3=swap etc etc! Once you've added the correct lines into lilo go to "/etc/sbin" and just type "lilo" that should then make the changes and tell you if it has ben added correctly or if there was a problem! Make a backup of the lilo file before you write it!

With the graphics problem and screen could be because you picked the wrong graphics chipset in the install. At the console type "xconfigurator" then you can change the configuration of your linux box! (just a little tip if you type "xcon" then hit {tab} it should finsih the command off as long as only one command will end with "figurator" if 2 commands end with just the "fig" part in it, it still wont work)

Still after deleting linux your lilo if still there. This is due to your lilo be written into the master boot record (MBR). Few ways you can clean this out. Best easy way I have found is using the only thing Bill Gates made that is good. A windows 98 startup disk. Put the disk in boot the computer at DOS prompt type "fdisk /mbr" That should clean your MBR. Don't have to boot from it but if you can't get to a DOS prompt any other way boot from if!

Well hope that helps you out a little.
