I think that as a newbie you need to focus on the basics. Find a speaker style that you like (horns, super-efficient, cones, planer, etc.). Find an appropriate amp to drive them (SS, tubes, SET, etc.). Find a preamp that compliments that amp. Find a source within your budget that has the sound you are after. Get some basic cables to hook it all up - stay away from zip cord but don't go overboard on price. Play with setup and room treatments until you hear what everyone is talking about tonally and spacially. Then enjoy yourself.
Once you have it all up and working and are fairly happy with the sound you can begin to play, or not, as your finances allow - swapping things in and out to see how they each affect the sound you hear and like. The expensive toys are primarily for people with extra disposable income and an urge to try and play - not always for improvement, and often out of sheer boredom, but sometimes out of the urge to learn and experiment.
It is a hobby and some people are super enthusiasts, some are musicians, some are engineers, etc.. Each has their different priorities, different ears and different amount of cash to spend. So just enjoy yourself and take it slow.
