The coil packs should be low in the front if you have a V6( just follow the plug wires). Yes, they are easy to replace on every vehicle I have done.

I have a 97 cavalier with a 95 engine and i had to replace the whole ignition module and the coil packs are 1/4 and 2/3 that's how they are numbered on the coil packs so 2 coil packs but make sure you know which one isn't firing to replace them and u will have to replace you spark plugs after that.
The newer style coil packs are no longer a maintenance item and don't really wear out. If one coil pack fails I usually just replace the faulty one. Unless there is visible damage or performance issues with the other coil/coils there is no reason to change them all.
there is no need to change the coil packs just to do routine maintanence
There are 8 bolts that hold it on. First remove the cover to the coil packs, Then the coil packs then the vallve cover,
they are under the coil packs which are in the top of the valve cover, unplug the coil packs, take out six bolts, the wires should come out with the coil packs and you will have access to the plugs.
the coil packs are held on to the brackets buy either a seven mm or 8 mm bolts on each side of the coil packs. if you have the twin packs on each side of the motor. now if you have to take the bracket off the you got, i think, 14mm and 15mm bolts down on the face of the heads.
