Most things do not matter.  You can do either way.  There are some
things that I have seen that must be modules and some things, like file
systems, that must be compiled in.  Example on the last one, I use
reiserfs for my files system including root.  If I have reiserfs as a
module, the kernel will not be able to read my root partition to boot
up.  For that reason, I have to compile it in so it can read the root
partition.  IF I had say a data partition that used XFS, I could make
that a module if I wanted to.  The system will boot up and then load all
the modules so it can read the other file systems.

One reason some use modules is that you can update them or do bug fixes
without rebooting.  You just unload the module, update it, then reload
it again.  This is usually something that folks like me and you do not
have to worry about though.

is before that date.  I'm not really sure either.

Save that info, you may need it.  The first kernel I made would boot up
but some things, USB and a couple other things didn't work, so I made a
new one.  The new one wouldn't work at all.  Something I changed didn't
work right at all.  Since I saved the old one, I just rebooted and used
it.  Otherwise, I would have had to boot the CD and chrooted in to fix
it.  That's a good tip to keep in mind.

Most likely the first one is named bzImage and that is fine.  Just name
you new one something different.  You can name it bzImage-1 if you
want.  I put the kernel version on the end so I know what version it is.

That means you have to add it to the /etc/modules.autoload.d/kernel-2.6
file for it to load the module when it boots.  This is what my file
looks like:

I guess I do still have my sensors as modules.  Anyway, nvidia has to be
a module.  You will see them when they load up.

Not crazy pills.  I'm disabled from a skin disorder and when it starts
to itch like crazy I can take meds for it.  It's just that the meds make
me sleepy.  When I get up, I have a really dry mouth and I want to eat
everything in the house, even some foods I don't like.  I took my meds,
just one pill though, so parden me while I go eat.  O_O
