Google ENCO for tools, they sell everything from cheap Chinese to excellent USA/Japanese tools.

You don't need special tooling for the bores, but knowing how to grind a special tool for something is a handy skill; in this case a tool with the cutting tip towards the left side would be fine for the bores.

As EricH wrote, your lathe has three wheels to move the cutting tool: The carriage (towards and away from the headstock), the crossfeed (perpendicular from the axis of the lathe, in other words front to back) and the compound. What EricH means is the compound, which can be adjusted to any angle you need. There are setscrews or screws that hold it in place, and a scale marked in degrees around it. Loosen the screws, move it to the angle you need, and tighten them up again (not TOO tight), then by turning the compound the tool will move at the exact angle you want.

Making a mandrel to hold the workpiece is a good idea, since chucking that hub with those flanges will be a royal pain otherwise. I suggested chucking it internally (inside the bore, pressure pushing outwards) but a mandrel sounds a lot easier.

By the way, that 3" material can probably be used; just modify the hub so the flange is 3" OD and the rest of the dimensions get smaller by a little. The 1/2" shouldn't make much difference.
