100mm f/2.8 macro might be too long for you.
for a longer macro lens, the only advantage is working distance betw. your subject and camera.
when D300 is attached, the lens becomes 160mm, it is really hard for hand-held during any of your macro shooting, unless you carry a tripod and use…
50mm/f1.4 is a very good lens, but 50mm/f1.8 is MUCH cheaper than f1.4, since you use it for DSLR, I believe you cannot tell different as far as imaging quality concerned.
if you care about a macro photography, go ahead for 50mm/f.2.5, so you can work on both a small world and your normal world. no need buy another 50mm lens.
