Spark plugs on a 3.4

Woke up early today to go to the stealer to get some plugs for the runner after lots of reading the past few days. They were 3 bucks each. I thought everyone else got them for like 2 bucks each???? Oh well. Since I dont have any place of my own to work, I just pop the hood and start working on the street where I was parked a few houses down. So I'm looking under the hood and everything looks jammed but the passenger side doesnt look that bad. Just take off the intake and with some manuevering and time, I finish the passenger side. Surprisingly every plug came out easily and didnt look that bad. Since I've done a bunch of other things with minimal increases in mpg I figured the plugs would be shot but they didnt look that bad. Ok next up is the drivers side. First outer most plug wasnt too bad either. Another surprise was that it was a denso plug. Since I got the runner used didnt think the previous owner changed the plugs but maybe they did since everyone said that one side was densos and the other is ngks. But at 70k they should be done again anyway. Now I'm pretty much stuck and have a few questions. First off, how the hell do you get to the two plugs closest to the driver? Theres so much junk in the way that it looks like you have to pull out everything. Anyone know what the bare minimal things that I need to take off or unscrew to get to them? Second, I dropped one of the clips that holds a hose and a wire together into the engine bay. Is that anything to be concerned about? Lastly how toxic is antiseize and dielectric grease? Got a good amount on my hands but think its all washed off. I think. Any help would be appreciated. 4 plugs down 2 to go. Unfortunately they look to be the toughest.

edit: Woohoo! Ok it was either due to lack of sleep, lack of food, or just plain retardedness that I missed the solution. After a little break and some food, I went at it again and this time it looked fairly simple. All I had to do was remove a bracket, a ground wire and move aside a hose or two and there was enough room to work with. That and about 2 ft of extensions and I'm done! Oh the feeling of getting something done and saving a few hundred dollars just rocks!

Seems as if all Yotas run the NGK and Denso combo. I wonder what the real reason is.

My favorite spark plug trick:

To install new plugs use a peice of 3/8" automotive tube. Stick the plug in one end and use it like a flex extention. Works like a charm in our cramped engine bays.

My cousin showed me this trick after fighting like mad to thread new plugs.

I actually used a 1/4" fuel line hose to put the new plugs in and it was a perfect fit. Another good thing to do is to use the extension only without the ratchet. Plugs were gapped at .044 I believe. Actually they came pre-gapped pretty well. Didnt have to do anything but didnt forget to check them too admist everything

I recently changed my spark plugs as well. They were Denso IK20 and came pre-gapped at 0.4". Is that normal?
