Yeah reason (or any DAW) can be a bit daunting when just starting out. I highly recommend watching some vids from the Props YouTube channel and many others that folks post on YouTube. Also if it seems overwhelming, just pick one device and dedicate an evening reading up on it and watching tutorials and having a play. Just chip away a bit at a time and next thing you know smacking the rack sideways!
Also as far as Reason 6.5 I personally think it's worth the upgrade, but you'll definitely want to spend some time with the manual and get your head around the new SSL mixer and some key features. Good luck!
