I was doing my tuneup and when I got to the plugs I got #1 to come out. but #2,3,and 4 seemed too stiff when I tried. So I was told not to force them b/c I could either snap the plug or possibly strip the threading in the block...I took the truck for a drive for 20 mins to warm it up and tried again and #3 came out, but I wasn't sure if I was screwing it up and kept going and it turned out okay. so I still have #2 and #4 to remove. Do I try again after running it hard for a longer time??(as in highway speed)

Just so you don't have to ask. YES! I'm an idiot and I do need you to spell it out for me.
Try spraying some BP blaster or something like it on them....It may seep down the threads and help.......
But without a doubt....when you get them out and replace them....put anti-seize compound on the threads before re-installing.
I do not think you will mess up the threads in the head by using some effort to get them out, unless the threads were cross-threaded when they were first put in .....and will have to be repaired anyway......if the plugs breaks when removing, no big deal, you are replacing them anyway.
You are not going to cross thread or strip it trying to get it out.....the reason they are so difficult to get out is that they may have been cross threaded going in......Most auto parts stores sell a thread chasing tool that can be used to clean up the threads once the plug is out if they are cross threaded, and it is not too bad.......If they are flat out stripped out.....the head will probably need to be removed and taken to a machine shop.....
Try the penertrating oil first and see if they come out.

Yes, definitely do the penetrating oil first. Try WD-40. Give them a good shot when they're cold. Spray them a few hours later...or the next day. Try and spray them a few times before you start the truck again. Keep in mind though that what doesn't evaporate off will burn off when you run the truck. So it might smell a little.
I'd try that for a few days...then try and turn them out. Hopefully, whoever installed the plugs just overtightened them...and didn't strip the threads. Since you were able to get some out, I'd say that your plugs are just too tight...not cross threaded.
BTW, I was able to remove exhaust manifold nuts this way. And trust me...no one likes rusty nuts.
I did a Google search, and check on Amazon.com for a "nissan spark plug removal tool"......did not see any kind of special tool. There are some spark plug sockets that are longer to allow you to reach in to the recess of some recessed plugs, and most spark plug sockets have a foam insert to prevent the insulator from breaking, but I did not see a special tool to make the job easy.....
I agree with Grug....In the OP's case I think someone just put them in too tight....there is a torgue spec for spark plugs....The head is made of alum. the spark plug base is steel.....put them in too tight you have a bear of a time getting them out....that is why it is important to use anti-seize compound on the threads when installing them and torgue them to spec's.....
Check and see if the Nissan toolkit is still in the truck. The kit includes a spark plug wrench that makes removing those plugs a bit easier. Also, be sure to blow out the plug holes before removing the plugs to keep all that crap from falling into the cylinder. I recommend putting anti-seize on the new plug threads when you put them in.
The tool I was referring to is to make removing the plugs from the V6 easier. The back plug on the drivers side is a bugger to get at and the Nissan tool actually makes it easier to get out. 4-cyl doesn't have the same problem.
