If you were to put a digital readout the X and Y axis would be the most logical. At this point though, your money would be better spent on basic accessories and tools. Look into hold down hardware for the table (studs and strap clamps), drill chucks, collets, angle plates, a rotary table, a dividing head, end mills, fly cutters, a decent milling vise, parallels, 123 blocks, drills, an edge finder, V-blocks, the list goes on and on...
