In a nutshell:

Open Source means that you can get the source and modify it if you wish. But to run it you have to compile those changes
The Linux kernel always has to be compiled to run, since it's the operating system itself and thus can't be interpreted like a shell script.
The Linux kernel is usually located in /boot/, look for a file called vmlinuz* or similar
Other system files, like libraries and essential executables are located in /sbin, /bin, /lib and /usr/lib. This include the glibc and alike
The Kernel source can be installed through your distributions source package, or you can download it from kernel.org

Again, if you want to start Kernel hacking, start by installing a distribution, getting used to it, move on to the command line and it's tools, so that you get a feeling for what the kernel does and how changes could affect it's behavior.
If you want a fast dive straight into it, start with Gentoo or Slackware, and later use that to build a LFS system.
