Welcome to VR mate! Set up your oculus account up now and and keep an eye on the 24 hour winter sales,2 games get heavily discounted and they change at 6pm, unfortunately you have missed some great sales but you still have a few days left. Also Steam have a great sale on too.
If you have a small player area, you may to get away without the need on paying for an additional sensor for 360 room scale games (which make VR sooo much better, turning your body in VR is much better than snap or smooth turning with a button or stick, it kills the immersion for me) it could be worth looking at getting a long usb extenders for the arrival of your Rift.
Edit: Have you downloaded and ran the oculus compatibility tool from oculus’s website??? The oculus rift is VERY fussy about USB’s if you haven’t, please do so ASAP, there’s very good chance you may need a pcie USB adapter, (inatech 4 port from the ‘rain forest’) I don’t want you to be as disappointed as I was when my baby came!
