Also go to the Hypertherm website where you can download user manuals for various Hypertherm plasma cutters. As others have said, the current and speed settings will probably be different to your plasma cutter but may at least give you a starting point.
In the pictures you supplied it looks like you have no torch height control so your plate will need to be flat and perfectly parallel to the machines X and Y axis. If you intend on doing thinner sheet your cut speeds go up, and there is a much greater likelihood of material warping. Without a torch height control you could have big problems there.
Go on Forums like Plasmaspider to learn more about cnc plasma cutting.
There's plenty free 2D cad software out there - Draftsight, SolidEdge2D, etc. Just Google free 2D cad. Also Inkscape for more "arty" type drawing.
Sheetcam is a great 2.5D cam software for plasma cutting, routing, drilling, milling, etc. Not free but not too expensive either.
One thing I'd check is how fast this table can cut. The controller looks extremely basic and I get the impression this table was originally a router and may have been converted to plasma use. If so, does it have the speed and acceleration necessary for plasma cutting. A look at the Hypertherm plasma cutter manuals will give you an idea of how fast the machine needs to cut based on what thickness material is being cut and what nozzle is being used.
Personally I'd buy a complete electronics package dedicated to cnc plasma and retrofit the table.
