Yes. It will auto focus on the D750 but when shooting close-ups, depth will be limited.

I'm curious, doesn't the Nikon 105 have internal focusing? I'm not familiar with the Nikon because I've only had Canon and Tamron macros. My Tamron 90 doesn't extend.
Yes the current version does have internal focusing but still the effective aperture is still affected. It's not as much as a lens that simply moves the entire lens in and out to focus which lose 2 stops when focus at 1:1. I can't find the information but believe the current 105mm f/2.8 micro maximum effective aperture when focusing to 1:1 is something like f/3.3.

IF also affects the working distance...

Yes the working distance of the current lens is a whole lot closer at 1:1 than the old 105mm f/2.8 micro AI.
Just fired mine up. 3.3 is correct. The lens is one of my favorites.

There is a lot of information out there but I recommend watching this video by Roman Kurywczak. He provides a lot of information on technique but also has an outside-the-box approach as well as a good sense of humor. You'll find his commentaries both amusing and educational. You'll hear him talk about using a 180mm macro lens with a 20mm extension tube and a 1.4x teleconverter, the use of tripods, no tripods, flash, pop-up flash, ISO, shutter speed, f-stop, etc. and his favorite L-bracket.

I just checked my Tamron 90 and find that it too is affected in this manner. Any setting below f11 loses about one stop at closest focus compared to infinity. Never noticed that in everyday use. I typically use this lens at f4 or f5.6, sometimes f11.
F11 will be your minimum , except for flat subject [ like a coin ] .so you will need a lot of light .shooting bugs in the wild will be mostly hand held .
First learn depth of field and aperture selection. Two ways to focus, 1) turn the focus ring till sharp and 2) set the focus and aperture for the DOF (image) you desire and use a fotill you get the focus rail to move the camera/lens assembly till you get the image you want.
Your not in the world of point and shoot anymore.
Sorry, I've been out-of-pocket the last day or so. I didn't realize there were all those other sections! I overlooked the (tiny) "All Sections" link buried at the bottom of the page. D'oh! Anyway, thanks for all the good advice ... looks like I've got some reading to do. This is such a friendly and helpful forum!

It may be helpful if you give some information as to what it is you want to learn from a tutorial. As with any lens, technique will vary depending upon subject and conditions.
Do you have a specific 'subject' interest and an idea of the type of images you want to achieve?

Looking for basic functional/mechanical techniques and "rules-of-the-road", if you will. I'm starting to watch some Youtube videos others have linked for me. Thanks for your response.
