Sinner,
I am starting out with the stock 3.8 pulley, 39# injectors, E-Force Competition Air Intake Kit and JDM Tune (of course). I already have 4.10's, TCI 3000 stall converter and an Cervini's Side Exhaust kit.
I have an 2006 and heard some horror stories about people with 05-07's breaking their plugs and having issues while taking them out. I did some research and I swapped out my plugs first before I did anything else. What I did was warm the car up for 10 min. then took off all the coil-on-plugs. I used an blow gun on my air compressor and blew off any dust and sand out of the spark plug area. I gave a shot of penetrating oil to ea. plug and let it sit for 5-10 min. Then I took the plugs out by torking them out two turns out and one turn back in, hence only backing them out a 1/4 turn at a time. They all came out without any issues whatsoever. After I got those all done, then i started from step one in the manual. The reason i did this was because I read that you should remove the plugs while the engine was warm to make it easier for them to come out. (You can't do that if everything is ripped apart.) I don't know what yr. your ride is but hope this helps. I just got the intake manifold off yesterday. I am putting in hrs. after work and I get any free time so this may take me about a week to get everything in. Let me know how you make out!
Peace,
Roger
