I studied and played with my 105mm lens for hours on Friday to try to get an image in full focus. Still fuzzy at edges. I bounced my (in camera) flash. Photos taken on a lens cloth.
Is this the best I can expect? I am never sure.

You have eliminated all of your Efix info, so we cannot know your camera/lens settings. What camera, lens, illumination?
Please re-post original, and check the box labeled "(store original)".

Your second image looks sharp, but I may be seeing noise in seed veining, due ISO 1600 & cropping.
How long is this winged seed? Can you please post original Out-of-Camera image, not cropped image? I believe that you can move closer for true 1:1 magnification.
Also, I believe that you have significantly tweaked exposure in PP, which adds to the noise. The jet black background may be fooling your "Aperture Priority" auto setting. You need to be shooting manual in strong sunlight or speedlight illumination, to allow a much lower ISO.

I agree with the comment about the black back-drop. I use one occasionally, and manual metering is a must, to avoid as much noise as possible.Also, I believe that you have significantly tweaked exposure in PP, which adds to the noise.

Thank you both - the original is 1 1/2" X 1/2" +/-
The next time I ask a question, should I post the photo out of the shoot/no embellishing? I never used to think about this stuff until someone pointed out my weak points. Now I am a little retentive. :)

I am sending you the originals. Thanks again. I'm not sure of all the terminology, but I'll catch up.

If your winged seed is 1.5-inches long (38-mm), and your D90 sensor is 23.6-mm wide, then you cannot shoot true macro of 1:1 magnification (life-size) horizontally. I suggest also shooting corner-to-corner, which will get you close to 1:1, if you practically fill the viewfinder corner-to-corner.Thank you both - the original is 1 1/2" X 1/2" +/-

I asked for OOC image just to see how much you cropped to arrive at your submitted JPG. Most novice photographers shoot too far away, then add noise when they heavily crop in PP.
I can see from your OOC image, that you cropped away 75%, keeping only 25% of pixels. This not too much, but much more than if you fill viewfinder corner-to-corner.
One image I could crop C-to-C, but not the second. Did you re-size your cropped images? Because my OOC crops are are much larger pixel counts.

Re: Diag.OOC shot
I usually shoot tight, except with this lens, I am not certain yet. As far as I could tell, the diag image filled the frame, I thought I was very close and trying to find the "sweet spot", I took the shot. Just so I understand, should I have been closer?
Staying on the diag OOC, I am not sure that I can grasp where a 75% reduction comes from, except that a diag. cut (as in sewing clothing) results in a lot of waste of material (pixels here). I also had turned the image sideways later and filled in the resulting blank edges.
I just re-cropped (attached) 4288X2848 original pixels to 3635x2196 just now, like you did. Is that the correct way?
I still do not know why this image was not sharp across, but I will keep trying to apply the suggestions until I get a Eureka! moment.

My d90 has 14k clicks on it never focused (no pun) on macro before- seems like maybe I did better when I didn't try so hard.

Thanks about the sunflower.........
That photo was taken with my "nifty fifty", automatic all the way, in camera flash! I guess sometimes less is best.
