4BTA Cummins Performance Modifications

I have a 95 YJ wrangler and I want to put a 4bt in it but we can never leave well enough alone can we?  So I want to get it up to around 400hp and 700 ft-lbs of torque if possible while retaining driveability.  This is probably the most important part as this is my daily driver.  After reading about the "Hybrid Killer" I know that a high hp engine can get good gas mileage.  

The parts of a 6bt 5.9 cummins are compatible with the 4bt and I was wondering what I should run for injectors, what lift pump, and if a hx 40 over an hy 35 as a compound setup would be any good?  If not, what would you guys suggest?  I would like to get as good of gas mileage possible with the power gains; that is my main goal.

Sorry for asking so many questions at once.  I am new to the diesel niche and have many.  If there is a good book that talks about diesel performance modifications, much like DieselPower has done with turbos (and other issues I did not get), in depth.  Thanks!
