If I may be so bold I would point out that the reason you're a bit under-informed could have something to do with buying from a mondo-mega-sports store. My experience has been that by working with my friendly neighborhood fly shop instead the staff might have already walked you through everything including the how, what, why and when.
I would first try to establish a relationship with a flyshop in your area. This will lead to many answers even to questions you didn't know you had
Do you have a fly shop nearby?
