So since I've been back from Florida I've been assembling the supplies to fix several issues:
Ordered Heat Shield and new Tranny bolts from Merlin at St Charles Isuzu.
Purchased a Tranny Filter kit for the GM transmission at a local Isuzu dealer (kit comes with both tranny gaskets and filter - they threw in two copper washers for the plugs).
Ordered the boot rebuild kit from Independent4x4
I also had a couple of maintenance tasks and wanted to address the poor design on the cup-holder Joe installed for me in place of the 6-Disc changer (also installed a new head-unit that I bought at a garage sale - Pioneer that has a USB input and controls an iPod.
The Heat Shield ended up being back-ordered so I'm saving that task plus the change of filter until that part comes in. I did want to drop the diff fluids and replace with Mobil 1 full synth which I've done recently - more on that later.
I received the package from Independent4x4 almost immediately, and since that repair seemed to be the most risky if left undone, tackled that on the weekend of 8/1. I finished the passenger side and then had an issue removing the lower control arm bolts on the driver's side so that waited a couple of days. There are some great write-ups on the general technique so I'll just hit some hightlights.
If you haven't seen what a torn boot looks like, here's an image - I'm spreading the tear so you can see the shaft inside - the tear goes all the way around both outer boots.

It's easier to jack up the whole front of the truck and support with Jack Stands (make sure they're rated for at least the 4000 lb weight of the truck) and pull both wheels off at the same time. Note the jack under the lower control arm on the passenger side - you need to relieve the spring pressure to get the bolts out (next thing you do).

The red arrow shows the bolts (there are four) that you remove.

Now comes the fun part and where the Mecatech boot kit is very handy. Since the inner boot wasn't torn there's a very good chance that that joint is fine and that you can just cut if off - remove the band closest to the differential and slide back to expose the greasy joint - there's a retaining wire you pop-out with a flat blade screwdriver or pick. This allows the whole joint to be pulled away and out - swing it to the back side and remove the inner band - you can just cut the boot off at this point - if you're worried about crud getting into the good joint wrap it plastic until it's time to reassemble.

Next remove the bands from the outer boot and cut away the boot. Here you cans see the bad boot cut from the joint. Clean off everything - I used newspapers to get the bulk of the grease off and save my rags (stingy I guess but it just seemed easier to grab more paper that could be tossed in the trash). Spray off everything with brake cleaner until it's all squeeky clean and examine for any damage - mine were fine.

Next comes the cool part - the Mecatech kit comes with these large cones - you cover with some blue KY-like lube (included) and slide the boot on inside-out.
http://www.modusmodern.com/blog/BootRepair07.jpg
You then fit the cone and boot over the inner joint and slide off onto the shaft - this allows you to bypass the inner joint so it doesn't have to be dissembled.
http://www.modusmodern.com/blog/BootRepair08.jpg
Do the same with the inner boot, only this time it's on the cone rightside out.
http://www.modusmodern.com/blog/BootRepair09.jpg
Lube up the joints with the supplied grease, fit the ends and replace the bands using the handy, included banding tool. Note that you have to "burp" the end so there isn't any deformity in the boot.
http://www.modusmodern.com/blog/BootRepair10.jpg
Do the other side and you're done - total time for the first joint was about 3-4 hours taking may breaks. I did side two about 4 days later and it took a little over an hour (knew what I was doing at that point).
Before putting the tires back on I have the backs of the wheels a good degreasing and clean-off - all the slung grease was stuck on like cement. I also wiped down all the suspension components so they didn't have all that gunk on there.
In all I think the MecaTech kit from Independent4x4 is the way to go - once you have the extra banding tool and cone it makes things much easier - they also give you some extra bands in case you need to make adjustments. I rate this on about a 3 on a scale of 1-5 for technical difficulty - mostly due to messing with heavy drive/suspension components which are ackward to move around.
