The switched outlet wiring configurations show two different wiring scenarios which are most commonly used.
The wiring and connections will depend on where the power enters the circuit. The
connections for a switched outlet also known as a Half Hot Plug.
The diagram shows the power entering into the circuit at the switch box location, then sending one power line for the outlet which is hot all the time and a switched leg for the top half of the outlet being used for a table lamp or a floor fixture
Switched Outlet Electrical Wiring Diagram #1
The Electrical Power Source Enters at the Switch
Outlet Wiring for a Table Lamp or a Floor Light Fixture
These electrical wiring diagrams show typical connections.
The diagram below shows the power entering the circuit at the grounded outlet box location, then sending power up to the switch and a switched leg back down to the outlet.
Notice that these outlets have the tab removed from the "hot" side or Brass side of the outlet which allows the top half of the plug to be controlled only from the switch while the bottom end of the outlet remains "hot" all the time. This is shown in the pictures below.

Switched Outlet Wiring Variations
The switch I am replacing has two red wires plugged into the back and two black wires plugged into the one below. If I want to keep the same set up I can just connect the two red wires to the top brass screw and the two black wires to the bottom but must break the small brass tab between the screws not the plastic, correct? If I don't care to use the wall switch all I have to do is to cap off the red and connect one black wire to one brass screw and one to the other brass screw without removing the brass tab, correct?
From what you have described, I believe that you are correct.
The brass tab can be left in place if you no longer want half of the outlet to be controlled by the switch.
How to Install Electrical Outlet and Switch Combo Wiring – In most cases, the primary power source is shared between the switch and the outlet, either with a wire jumper or the bridge or tab that is located on the side of the combo switch and outlet.
How to Wire Half Hot Switched Outlets: The brass tab is a link between the top and bottom receptacles that allow them to be isolated from one another for applications such as a wall outlet that has one receptacle controlled by the wall switch while the other receptacle is hot all the time.

This is a testing tool that is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
This is great to troubleshoot a problem with outlet circuit wiring, is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets
Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency
Lights indicate if wiring is correct and indicator light chart is included
Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect, Very handy and easy to use.
A wire stripping tool used to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets.
