The second guide looks better, read it through before you start. If you have problems, 9/10 you've made a bad selection during the configuration.
Not many succeed the first time they do a custom compile, but if you keep trying and you manage to make a good configuration, it is certainly worth the trouble.
btw. once you have a good configuration, save it for later, it is in the .config file in the /usr/src/linux directory, but I expect the guide to tell you all about that
