I know what you mean about being nervous.  I am new enough to linux that
quite a bit scares me too.  Even though the boot process is one of the
scariest things (everything else can be avoided!) it is usually easy to
remedy anything that can go wrong. You could, for example, boot up your
Windows disk and go into rescue mode, type FDISK /mbr and you won't see
linux anymore allowing you to re-install.  You could find a floppy
version of fdisk (for linux) this would allow you to delete all your
linux partitions and you could start over from scratch. But I digress...

You don't have a grub.config file because you have never installed grub,
only LILO (that's what I remember from your last post - correct?).  I
guess your best course is to proceed -- cautiously!  Try booting into
your windows CD, type Help FDISK you should find all the info you need
if you end up needing to start this over. You could back up all your
data just to be safe. It wouldn't hurt to type man grub-install so you
know what it will do for you.  Once you're sure that all it will take is
a little work - go for it!  Do the grub-install, (Keep your fingers
crossed).

Good luck
Scott
