Display can be turned on/off in the 'advanced options' for ephemerides. When turning them on, you can select from various format choices (base-60, decimal, different precisions, etc.) Distances are in kilometers for distances under one million km (about 0.00668 AU), and in AUs for larger distances. Uncertainties are one-sigma values shown in arcseconds (unless they are very large, in which case they are shown in arcminutes or degrees). In theory, the object should be within this distance of the nominal RA/dec 67% of the time, within twice that distance 95% of the time, and within three times that distance 99.7% of the time. In practice, astrometric errors are not actually Gaussian, which means these uncertainties are sometimes over- or underestimated. So you may have to look farther, or not nearly as far, as the uncertainties say. The object will probably be offset from nominal somewhere along the indicated position angle, especially if the orbit is well determined.
