Welcome and congrats on the purchase.
The way to check the fluid is: raise the car up so it's level (put it on 4 jackstands on a level surface), and open the fill hole bolt (the one from the side -- horizontally, not the one on the bottom). The fluid should be right to the bottom of the hole (meaning if you add any more in, it starts dripping out the hole).
The procedure for changing the fluid is simple too: open the drain plug on the bottom, let it all drip out, reinstall the bolt, remove the fill bolt on the side, and keep adding until no more can go in. Then put the plug back in.
edit: If you don't have 4 jackstands, it's probably cheaper to swing by any shop and have them change your fluid. Don't go to the dealer ... anyone can do it, but do get the proper spec fluid.
