No, don't hand edit.

What I do is as the book states:

make menuconfig
make modules_install
cp arch/x86/boot/bzImage /boot/vmlinuz-<current-ver>
cp .config /boot/config-<current-ver>
cp System.map /boot/System.map-<current-ver>

You are not overwriting the distro's config, you are copying your custom 
config to a new file name in /boot.  Change <current-ver> to make it a 
unique string.

Don't use your distro's .config.  They build virtually all possible 
modules as modules.  That means you need an initrd for simple things 
like ext3 partitions, the build takes muck longer, and it is huge.

Read the hint referenced in the book about how to configure the kernel.
