Got a cracked block

[Ground hawg]

OK, from the heading most of you have figured out what I gota do. yep change the Engine.
So here's the question(s)

1) what equipement is required for the removal and replacement. (anything special)

2) for a guy with a resonable amount of brains, roughly how long should I expect it to take.

3) with the engine out what upgrades would you concider for the new engine(6.5 t/d in 99 wagon).

4) anything tip's you can give(exept takin it to a dealer, no way am I paying $14,000. for someone else to do it for me)
