Bump steer is entirely a factor of the placement of your track bar ends vs. drag link ends. Most people either keep both stock, or raise 3" on the track bar and flip the drag link (although this isn't necessarily "ideal" at all lift heights, but it's pretty close and what parts are available for).
Return to center is pretty much entirely castor, given a specific power steering configuration. Stock vs. hydro assist vs. full hydro will all have very different return to center characteristics, but that's a separate design decision.
Crispness is going to be a factor of what condition your gear box, ball joints, and link ends are in (any slop will make it not feel crisp) and toe-in.
Wandering is a factor of all of the above, as well as tire pressure.
So basically, maximize your castor without killing your drive shaft (pretty limited with a stock axle housing, but get what you can get), set an appropriate toe-in, figure out what tire pressure feels good, and make sure your drag link/track bar are either flipped/3"-raised, or factory/factory. This will get you the "best" steering you can get without going into custom design work, new axle housing, etc. Also, IMO go hydro assist for the best steering feel, but that's very much an opinion and some would disagree.
