I have an 88 Mustang GT 5-speed and it is not running right at all. It
is like it is overloading. You can smell fuel real bad through the
exhaust. When you rev it up really high it will back fire and it is
also missing. I've changed the fuel pump which I had to anyway and I've
also changed the spark plugs. Can anyone help?

did you read the plugs? That will tell you which cylinder if you have a
bad valve etc.
change rotor cap - do a tune up
The fuel pump is inside the gas tank, you changed that out? Why?
change the O2 sensors
read the codes out
don't rev it up over 5500 ever if a daily driver.
put in a new coil.

Since I am a girl, I am not scared to ask how do I read the plug's and
where is the 02 sensor located?
The fuel pump was changed because it was bad.

Go to your auto parts store and buy a Chilton's or Haynes repair manual for
your 88 GT. Those books have pictures of plugs ranging from normal to
detonated to rich, to lean, etc. Just compare the plugs from your car with
the pictures. That book will also tell you where the O2 sensor is (exhaust
manifold).
I hope you saved the plugs when you changed them, and know which cylinder
they were in. Also, did you gap the new plugs?

There is also a troubleshooting section in the back that gives suggestions
for symptoms.
