Nikon's AF-D series 50/1.4 and 50/1.8 are not very flattering imagers....the bokeh is poor on both of those lenses. I would not buy either of them new, but only used. And like I said, neither is a flattering imager for portraiture....this is true of most 50mm lens designs; high sharpness, so-so rendering. If you have no autofocus, on the smaller Nikon bodies, the viewfinder quality is not as high as on the pro Nikons, and manual focusing can be tricky for many people. But....if you do want to go manual focus,and you want a lens that's a useful portrait lens on a D60, my money is on a lens that was made and discontinued before you were born Patrick: the 70-150mm f/3.5 Nikon Series E. It's a nice and light single-ring zoom lens; you can zoom out to 150mm where the magnification is high, and then zoom back shorter and shoot. The area between 70mm and 85mm is quite useful to have on a 1.5x body. The lens is light, affordable, and very sharp, and is optically good enough to migrate forward.
In my book, a used 50mm f/1.8 AF-D Nikkor is a "pawnshop lens" or an "e-Bay lens" that you buy on a clunker like a Nikon N6006 for $55; keep the lens and throw away the camera. The last 50/1.8 AF I bought was from a pawnshop, four years ago, and I payed $40 for it in mint condition. I would not buy the 50/1.4 G just as a people lens.
Manual focusing on baby Nikons is somewhat difficult for me with lenses in the 20-24-35-50mm lengths, due to low magnification and the cameras' built-in viewfinder screens not being optimized for manual focusing. Longer focal length lenses, like 85-105-135 primes allow easier manual focusing---especially if the lenses are older, manual focusing lenses, which have longer focusing ring rotations and allow precise manual focusing. Some lenses, like the classic 105mm f/2.5 Ai or Ai-S are very easy to manually focus. Your comment about the focuysing arc on the Tammy shows that you are aware of just how cranky many AF lenses are when manually focusing them.
The real problem though is the area between 50mm and 85mm is quite a wide expanse; it might not seem like it is, but the difference between a 50 and a 55 or a 60mm lens is pretty wide; at each of those steps, the angle of view changes quite a bit and the 1.5x FOV factor makes it even more-pronounced. This is why I am suggesting the 70-150mm f/3.5 Series E as a portraiture lens; it has a lot more range than many lenses, decent look to its images, and pretty good manual focusing.
The other alternative is to look at the Sigma 50-150mm f/2.8...that's probably going to be your best choice as a portraiture lens in an AF lens
