Alright, I just did this recently so if you are doing it and need some tips you can AIM me at bvvaffle. Air tools are good to have. As far as I remember the torque value for the flywheel is 105-110. However, you should definetly check the factory service manual for all the small steps. It has alot of info that I doubt anyone knows off the top of their head. If you don't have a manual, search around, there are free ones for download and they have been linked to in these forums before.
Make sure to have alot of shop towels to wipe your hands with. Also remember to get some lithium based grease.
As far as the pilot bushing is concerned, I would replace it if you already bought another one. I learned a little trick from a guy at a NAPA store on how to get the old one out. There is some space behind the old pilot bushing. Take a bunch of lithium grease and fill that space with the grease. Make sure to fill it up well, when you first put some in there will be air stuck inside so play around with your pinky and try to get all the air out and the space totaly filled with grease. Now take a woden dowel (round, long piece of wood) that has an almost identical diameter as the inside diameter of the pilot bushing. To find this I brought my new pilot bushing with me to home depot and tried to see what's the closest fit. Slightly bigger is better then alot smaller. You can always trim the wooden dowel if it's too big but you should be able to find one that's just right. So you take the dowel and put one end into the old pilot bushing and then hit the other end with a hammer. The dowel pushes the grease which has nowhere to go besides to push out the pilot bushing. If it didn't work, you didn't pack in enough grease. It took me less then 5 minutes to take out my out pilot bushing this way.
Now before you install your new pilot bushing, make sure it slides onto the transmition shaft fairly easily. If it won't slide on at all, you might have to file down the inside a little bit. Once you're sure it's ok, hold it against the hole it's supposed to go into and hammer it LIGHTLY. When it goes in far enough that you can't hit it with the hammer anymore, take a socket that's similar in size to the bushing and hold it against the bushing and then hammer that. Keep going until you are sure it's not going in any more.
