Hello,

Removing the spark plugs and coils on the left hand side of the vehicle, can be done very easily. As you will have direct assess to the coils. After you remove the coils you will be able to remove the spark plugs using appropriate size spark plug socket with an extension.
In order the remove the spark plugs and coils on the right hand side of the engine, you will have to remove the upper intake manifold. Which will require taking off all the mounting bolts for the manifold (see diagram).

For the oxygen sensor you will need to use a oxygen sensor socket. Your vehicle have 4 oxygen sensor. Two before the catalytic converter on each side of the engine and two after the catalytic converter.

The throttle position sensor is located on the side of the throttle body.
It can be removed by take off 2 bolts that mounts it to the body.
I have attached diagrams for your reference.

Please let me know of any questions.

Thank you.
