Congrats to the OP! I was going to say "shop" since you indicated you're a novice, but also to look around try a few shops to find the one whose owner and managers seem to really have your best interest as a rider at heart, versus just being really good salespeople. Hopefully you live in an area where there are multiple LBSs you can compare (I'm fortunate enough, in West L.A. to have dozens, most are friendly, some not so much, and others exemplary).
It looks like you may have found a good one, so congratulations on the bike and looking forward to your pics!
If in the years to come you get more comfortable self-servicing your bike for routine upkeep like cleaning and lubrication and light cable adjustment...or if you go even further down the rabbit hole and learn how to completely disassemble and reassemble your bike, then you can opt for getting best "bang for buck" by ordering frames and parts online and assembling them yourself. But until then, a good LBS is worth its weight in gold. And a great one should reward its repeat customers with a bit of a break off of MSRP.
