What kind of breadboard and prototyping board do I need to fit this right-angle DB25 connector?
I'm new to soldering and don't know what the standards are. Additional information on this subject would be helpful as well.

That type of staggered pins are more or less standard because they must also fit straight-through DB-25 footprints which are standardized, but you need a protoboard that is designed to hold them. This image was the first I found on google, but you can find them in all shapes and forms. This is for DB-9. Note the odd staggered part to the right:
Since the normal protoboard spacing is 2.54 mm while the DB-25 pin spacing is 2.77 mm, you need to search for a dedicated DB-25 protoboard. It could be easier to buy an adapter board which includes the correct connector, but have pins or screw terminals at a more convenient spacing.
Another possibility is that you could find an old ISA prototyping breadboard with 1 or 2 DB-25 connector pads. The advantage of this breadboard is the size of the breadboard available for you circuitry. Thought is was designed for PCB compatible ISA slots the connect is easy to find and you could wire it for your own use.
Radio Shack used to sell them but I believe I have seen them around on sites that sell surplus electronics from time to time.
