Where are they? On the top center of the valve cover.
Your questions reflect some inexperience (please don't take offense if not), so here are some tips.
Let the engine cool completely.
Carefully remove the plug wires, noting where they go BEFORE removing.
Blow out the plug wells so nothing falls in when removing the plugs.
Using the proper socket, remove the plugs, noting any 'tightness' after the initial loosening and being careful not to strip the head if they are.
Compare the plugs before installing. Look for the same length, thread length and tip shape. visually check to make sure none of the gaps are closed up.
Coating the threads with anti-seize is debated, but I always do it on aluminum engines. A little goes a long way.
Start the plugs by hand, using the socket (if it has the rubber inside) or an old plug boot.
Finish tightening with tools, a torque wrench is a good idea.
If you have some di-electric grease, use one of the old plug ends to coat the inside of the wire boots. This will keep the wires from sticking the next time you service the wires or plugs.
Install the wires, making sure they are in the same place and not rubbing on anything.
Check all the fluids and air filter.
Service the throttle body, if it hasn't been done in a while.
A battery disconnect and quick learn (with advise to your wife) would let it learn the new operating conditions. If any of this isn't something you've already read about, search for it here.
Have fun getting into the karma of doing it yourself.
