Replace all 8 injectors 2006 6.0L

In the very near future I will be replacing all 8 injectors on my 2006 Ford F-250 6.0L. The truck is out of warranty at 150,000 miles. The truck's symptoms are lack of power until warm, misfires until warm (even in warm temps), hard starting condition, excessive smoke, raw fuel odor. If you don't mind, I have several questions I would like to post before I start tearing into this project. Over the last several weeks I have been using the search feature for the answers to these questions, but I'm stumped! Thanks PS.org

#1: Could someone please forward me the Ford shop manuals for this procedure? It would be greatly appreciated!

#2: Do you recommend also replacing all 8 glow plugs considering the mileage on the engine and the inexpensive part cost? Also consider that I will have many components out of the way already.

#3: If yes to #2, could you please confirm I have the correct Ford P/N for the 2006 6.0L glow plugs? The P/N I have is 4C3Z-12A342-AA.

#4: Diesel Power Magazine recently stated in an article that the '06 model year 6.0L commonly experiences failed o-rings on the oil rail plugs. My question on this is two-fold; A: Will I even be removing the oil rail plugs to replace my injectors, and B: Do you recommend replacing these o-rings "while I'm in there" for peace of mind? Please also note that this truck does not currently experience the symptoms of a failed oil rail plug o-ring, AFAIK. Please see this link from Diesel Power Mag: 6 0L Ford Power Stroke Engine Oil Rail Plug Photo

#5: What is the correct fuel pressure PSI? I have searched high and low and have not had any luck finding this.

#6: Finally, are there any other "while I am in there" items that I may be forgetting? I am really trying to do my homework on this before I remove the first bolt, so as to address any other items that may become an issue in the future.

Bump! I think I found the answer to #5 (taken from another thread found here):

i would go down to ford or if you have a buddy with like a snap on scanner and do an injector contribution test first. you may only have 1 or 2 bad injectors. install isnt too bad i have done it about 4-5 times.

after the contribution test i would buy the amount of injectors you need to replace and buy the oem o-ring kit from ford.

dont worry about the glow plugs you shouldnt have to replace them.

Ebay. You can snag either the paper copies or DVDs. I prefer the DVD, since I can print out the instructions, get em all greasy on the work bench, and toss them after the job is done.

Would something like this have the workshop procedure I am looking for? I want to be sure before I buy:

Yes, FICM was just recently replaced, approx 1-2 months ago. FICM was replaced due to no-start condition and all 8 cylinder low contribution codes.

You need to get to the root cause of the problems. It could very well be fuel pressure ralted. I do not believe you will have access to the high pressure oil rails when replacing injectors.
