Nothing wrong with asking these questions here, as you will get plenty of advice, most of it good, but that should not substitute for taking the bike to the LBS and getting their take on what your bike needs. It could be an adjustment issue or a lubrication issue or maybe something else that they could spot. They should be happy to give you some pointers on the kinds of maintenance you can do and what you might need help with. The shop I use offers free adjustments for a year on new bikes they sell. Different shops have different policies, but any shop should help you keep your bike working right and avoid letting problems develop.
