Also be careful with how much torque you apply to the hex nut, if you over-tighten the nut you will crush the olive. I've done this twice. I guess that's why they include the crowfoot wrench so you can use a torque wrench to properly tighten the nut.
I suppose I'd know if this happened? I assume by mineral fluid leaking as soon as I over tightened it? Think I may have actually avoided this problem (and I'm a chronic over tightener) simply by counting the amount of threads that was showing where the hose is connected to the caliper, and then just trying to duplicate that when screwing in the hose to the lever.
Either way.. rear brake is installed.. build on hold until my carbon paste and grease arrives from Jenson. Hopefully tomorrow. Today, I'll be researching where exactly you want to apply grease, carbon paste, and loctite throughout the build. I'll post my findings in this thread for anyone else that may not know.
After a bit of research, here is the grease and carbon paste and loctite I ordered. Great reviews for all:

I was able to come to what seemed like was close to a consensus, so I'll attempt to summarize below. If I'm mistaken, plz feel free to call me out.
Loctite: Okay, seems this will used rather sparingly and used mostly as the need arises. I personally used loctite on the screws that attach the metal rear drop outs to the bike, the bolts that attach the brake caliper to the bike, and on the screws that attach the brake rotors to the wheels, and on the screws that hold your derailleurs to the frame. That's it. Apply just a small amount to the screw or bolt and then you can use it immediately - no need to wait until it dries. Also, on the dropout screws, I took the advice posted earlier in this thread and applied loctite to the threads, and a small amount of grease to the head/base of the bolt to avoid any potential future creaking issues. That probably isn't necessary, but it seemed logical so i went with it.
Carbon paste: Also used sparingly. To the point that Carbon_Dude hasn't used any at all on either of his chiner builds, so it may be entirely unnecessary. Although, I will say that after using it, I could see how it could definitely allow you to use less torque on the handlebars and seat post clamp if you're worried about your carbon bits. From the research I've done, seems like it's a good idea to use it, but I wouldn't stress it if you don't have any. Maybe buy some if you start to have slippage issues. I've only applied it to the handlebar and seatpost, and that's it.
Grease: This is probably obvious to many but I didn't realize that you were supposed to grease almost every screw or bolt (use your finger, just a very light coat) on the bike except for the places I've already mentioned above. You'll also use grease on your headset bearings, and on the steerer tube before you seat the crown race. (more on that on the next page of this thread)
Take note that many components come with bolts that already have grease or loctite applied. Obviously, if it has one.. don't apply the other. That's a pretty basic summary, and I'm certain I'm leaving something out, but that should help any fellow newbs get a better understanding of where to apply the various compounds. Feel free to add your input.
