Did you look at the help in the kernel makefile:

	make help
will show you what the different options do.

localmodconfig makes a kernel configuration based on your system and the
modules loaded, which is much smaller than the "full distribution"
kernel build, for all hardware in the world, which you don't usually
want for your own development.

There's also a whole book, free online, Linux Kernel in a Nutshell, that
describes how to configure, build, and boot a custom kernel, that might
help you out.

Then experiment away and see how it goes!
