I was finally able to get my LX450 coils, shocks, and new sway bar end links installed this past weekend. I wasn't able to get the extended brake lines installed because my wife wasn't around to help me bleed the brakes but I am hoping to get that done sometime this week. I also wasn't able to install the panhard drop bracket because I don't know how to weld so I will probably take it to a local off road shop and have them weld it on for me.
Overall the install went pretty smoothly but it took me a little longer than I expected (about 5 hours from start to finish). It was a little tricky to get the axle to flex enough to replace the coils since I was just using a floor jack and 2 sets of jack stands. Also, it was also a PITA to get to the top shock mounts to get the bolt on and off. Since I have a 1.5" body lift, I was able to reach my hand through the gap in the frame and the body to get to the bolt, but I can't imagine trying to do it without a body lift. There has to be an easier way to get to that bolt, right?

New sway bar end links - Rather than spending over $100 on extended sway bar end links, I build mine using trailmix's thread:

The final product, I am really happy with the result! (Sorry for the crappy pictures, it was dark by the time I finished everything up and Hurricane Sandy has prevented me from taking better pictures over the last couple of days so there will be more to come).
For anyone doing this with a floor jack and jack stands, here is the easiest way that I found to get the axle to flex enough to get the old coils out and the new coils in:
1) Remove the lower shock mount and sway bar end links
2) Using a floor jack (I would recommend at least a 3 ton) positioned at the lowest point on the frame (I used the gas tank skid plate) jack the truck up as high as the jack will go.
3) Place a set of 6 ton jack stands under the frame (I placed the jack stands under the factory trailer hitch) and allow the jack stands to support the frame.
4) Use the floor jack to raise the rear axle
5) Remove the tires
6) Use the jack to raise the rear axle as high as it will go without lifting the frame.
7) Place only one 3 ton jack stand on one side of the axle (I started with the passenger side)
8) Slowly lower the jack (This should cause the axle to flex since only 1 side will be supported)
9) If necessary use coil compressors to remove the old coils and install the new ones (My old coils didn't need to be compressed very much to get them out, but the new ones definitely did)
10) Use the jack to raise the rear axle again
11) Switch the 3 ton jack stand to the other side of the axle and do the same on the other side.
12) Reattach the shocks and sway bar end links and put the tires back on.
