i'm not 100 percent certain so be careful, if your doing all that you may wanna look into some gaskets while its apart, easier when that stuff is out of the way then doing it in 10000 miles and taking it all apart again

you don't have to, but you may find it beneficial to pull the heads and intake and replace the head gaskets, intake gasket, and valve cover gaskets while its out, and the glowplugs as well. if your not running the motorcraft glowplugs you will definitely want to try to change them while the pump and injectors are out, and they are notorious for breaking off in the head which means you'll have to pull the head to fish out the pieces, if your tuning up the injection system its going to be alot easier to tune everything up at once instead of trying to do it later on. just my .02

The CDR valve is held on by two bolts that attach to the back of the intake manifold. Remove the two bolts and lift up on the CDR while twisting. Soak it in gasoline for a little while to clean it out.
Don't replace any intake or head gaskets unless you have the engine out of the truck and want to do it for PM or you are having issues with them.

No, the motor is still in the Van so I won't be doing head gaskets and all. Thanks on the CDR, I didn't know much about it. Truck was getting harder and harder to start, and lose on power on the slightest grade. This van set alot over the years, and other then what I said about it, its good. Dose use oil, and the front seal on the trans leaks, and the gauges don't register for fuel right. I need to repair this for work. I've had cancer the last 5 years so I've been out of it, but am getting better now. Thanks you all for your help.
