Its not often i post in here but i do browse daily and learn a fair bit. Having read through this post, at the very basic questions you have needed to ask, i really don't think (and if this sounds harsh i apologise) that you should really be dishing out advice to new N900 users. I say this because you tend to ask "what to do" questions, as opposed to "how/why does this work". Which means you are not in a position to teach.
for example getting the answer to the question about Swappolube, "i hit apply but now the boxes are unticked, what should i do?" does not really mean you understand why lowering that swap value (among others) increases the speed of things. And as for overclocking....
Don't get me wrong its admirable that you want to help people but i recommend leaving it to the people who answered your questions. Otherwise its just the blind leading the blind.
