Actually, I Just made the part number list for reference. This site is amazing! Line it up with the FSM for reference and you can find pretty much any exact part!

This list of parts is $207 shipped from courtesy and $194 from mynissanparts. Unless I can use one of the cheaper bearings this seems about as cheap as it can be done. I believe this includes all necessary parts. (Not sure wtf assy means versus just bearing, that it includes races? The regular bearings look like the do too though???)
Outer Seal (Seal-Dust)
40227-50Y11
40227-50Y01
Inner Seal (Seal-Grease)
40232-50Y10
40232-50Y00
Wheel Bearing (Bearing Front Wheel)
40210-50Y05
40210-50Y00
Snap Ring (Ring-Snap)
40214-50Y00
Wheel Hub (Hub Road Wheel)
40202-50Y00
40202-50Y10
Using the following wheel bearing instead of the OEM specified one would make the total $184 using courtesy for the everything but the bearing. Not a huge difference. Paying shipping for bearing from some place else makes it not worth it?
