The SVT injectors will not work unless you get a new MAF calibrated for 19lb injectors, or have a chip custom burned for them.
The fuel rail is different starting in 1998, so I don't know if that will work with your 1996 without some modifications.
The throttle body does not have to be changed, but for the upper/lower to do their job, you'll want the bigger TB. The TPS sensor connector changed in 1998, so you'll have to figure that out. You'll also need a new throttle cable and bracket for the cable in order for the TB to work.
