The OMS engines on the shuttle (there are two) are two hypergolic propellant powered engines used by the shuttle during ascent, orbit and deorbit. During launch, the engines MAY be used after main engine cutoff to boost the Shuttle to a predetermined elliptical orbit. This is called OMS-1 burn. OMS-1 may not be required based on the payload and mission. OMS-2 burn is used to circularize the elliptical orbit that the shuttle first enters after launch. The engines may be used to change the shuttle's orbital characteristics during its mission. The engines are used to deorbit the Shuttle so that it may reenter the atmosphere to come back home.
The space shuttle had two kinds of rockets for maneuvering. The Orbital Maneuvering System (OMS) is used for changing the shuttle's orbit. When the main engines shut down, the shuttle is not completely in its orbit, so the OMS is used for final orbital insertion. The OMS is also used to de-orbit for landing. The OMS design is based on the rocket engine used by Apollo to orbit the moon and de-orbit the moon for return to earth. There are two OMS per shuttle, on the back just above the main engines. The OMS are on swivels (gimbals), which allows pointing them in slightly different directions to rotate the shuttle when they are active. When the other engines are not active, the space shuttle turns itself to point in different directions, and makes small motions such as to dock with the space station when it is already orbiting near it, using the small Reaction Control System (RCS) engines. There are 38 primary RCS engines, 14 in the front and 24 in the back, pointing in all different directions so the shuttle can move in all different directions when it is docking with something or wants to change directions. There are 6 smaller vernier RCS engines, 2 in the front and 4 in the back, that are used for fine adjustments. If the OMS engines fail, the shuttle can still de-orbit and land using the primary RCS engines in an emergency mode.
the higher the orbit, the longer the period. so it'll be longer
The space shuttle normally reaches 17,500 mph to go into orbit.
The shuttle never has and never will orbit the moon.
The shuttle does not fire it's engines in space, it only fires orbit adjusters.
Main engine cut off or MECO is when a space shuttle reaches the orbit and the external tank is jettisoned and the all 3 SSME (Space Shuttle Main Engines) are turned off

I know that in orbit, the shuttle goes about 17,500 MPH and reaches its top speed of Mach 25 upon re-entry.

The first stage would be launch of course, which uses the main engines (three liquid fueled rockets) and the two Solid Rocket Boosters that are ignited right after the main engines start. After 2 minutes the Boosters are done and are released, while the main engines continue until the shuttle is going fast enough for orbit. The total time from launch to orbit is 9 minutes.
It initially takes a large amount of energy to overcome Earths gravity. The aluminum oxide rockets get the shuttle moving and once they are lit up they burn until done. The liquid H2/O2 engines burn in a controlled, steerable manner to control entry into orbit.
Rocket fuel. Liquid Hydrogen plus Liquid Oxygen were the fuels used in the main engines for the space shuttle. That's what was in the big orange tank the shuttle rode into orbit.
The shuttle never has and never will orbit the moon.
The Orbiter Maneuvering System or OMS are two small engines (smaller then the Space Shuttle Main Engines) that allow the orbiter to lower or raise its orbit during a mission. It is also used to slow the orbiter down for re-entry.
