Im gonna buy mine soon before my cold air intake for sure, then im gonna have my tuner order me some plugs, he get the NGK 6's cheap and would sell me some for like 20 bucks, he offered me some msd plug wires, but I told him msd causes misfires in our systems mostly, so im thinking taylors that he has, dunno, maybe just oem.

Where did I get what from? I won a full set of Bosch Iridium plugs off ls1tech so I figure I will give them a shot and see what I think.
from a member on here from his 3.5 Monte. I have heard good and bad but I will see they are worth a shot since I got them for free. If I have to take them out oh well. Ill get some different ones.

Are you really sure you want put 3" piping on your car? You've already lost some bottom end power with that 3" downpipe. Additional 3" pipe will just take more bottom end away. You'll see improved performance in the higher rpm range, but coming out of the hole the engine is going to fall on its face. You want to keep exhaust velocity as high as possible to aid in scavenging the cylinders. The larger pipe decreases velocity and makes it more difficult to purge the cylinders. That means more spent gases are left in the cylinder. This dilutes the incoming charge and the result is less power. Once you get the rpm up to a point where proper scavenging begins again then you will regain the lost power, but like I said that will be further up the rpm range. The problem is with 3" pipe by the time you get the rpm up enough to regain that power you will probably be redlining the engine.
Bigger isn't always better. Here is an excellent read that will give you a better idea of what I am talking about:
