Questions 1-3:
A few months back Mini Truckin showed how to bag a toyota truck(same clip as you have) The photos an write up were good and it used all stock parts. If you don't have the issue it might be in the tech forum of MT's website. If you can't find it online post back and lemme know, I'll get you the year/month of the mag so you can order a back issue.
Question 4:
Barely Legal Fab will make you a uniball setup with tapered mounting hardware and uni balls mounted to plates that are drilled to match your stock ball joints so it all bolts in like stock. Be aware that the stock Toyota ball joints will support about 13 inches of wheel travel which is probably more than you will be able to get with an airspring. The key with using the stock joints is to re-angle their mounting so that they are just a hair from being bound up when the truck is layed out so that you have all their travel to use as you lift.
Question 5:
Most engines are designed to be tilted slightly to the rear for oil drainage, like a couple degrees. Bear that in mind when you mount it and you should be fine. There was a question about this in the Ask Max forum in the lkast week or so you could check out as well.
I hope my little book helps you out a bit anyways, good luck.
