Am I missing the point of Buddhism?

I have been on a few forums and Facebook groups and a lot of people on there seem to be missing the point of their practice. What colour robes should I wear, how many breaths should I take per minute while meditating and (worst of all) what is meant by this word, in this particular translation, of this sutra. No offence to anyone else here. In "Hardcore Zen" by Brad Warner he make some comment about the people who go to the temples, sit there meditating all day, but for all the wrong reasons. The principles are fairly self explanatory and as long as you live a good life as a good person, that is it. Enlightenment aka "the same old, same old". I know my life won't realistically be any better if I won a million punds and I am happy with that. By all means swot up on the methodology but it will just make you a better "buddhist" as opposed to making you any happier. Am I missing something? I hope not.
