I think you are along the correct path but there are a few changes I would suggest. Instead of keeping the coil buckets in the front, just ditch them in step 1. If you actually use the truck, you will destroy them on a noise dive. I know you only have the 4 banger and its lighter but still, the buckets just suck.
Secondly, switching to the Titan bolt pattern is your best bet over the Frontier one due to wheel selection. I would use the Titan spindle/hub with brakes in the front and then a Titan m226 in the rear but you will need to get gears from superior (probably the 4.56 ratio to help with your larger tires).
Lastly, don't forget you will need to figure out some kind of Master Cylinder swap (probably from a Titan) to make the larger brakes work and to help while offroading.
The only other thing to remember is that the front and rear fenders will get in the way if you have enough travel so some kind of fiberglass fenders will be needed.
Lastly, have you checked out other options for the rear? Something with swing arms and coilovers? This may or may not be in your budget but will defiently push the limits of your truck.
Also, is this build for a specific class or just something you want to do for yourself?
