Matt, I'm now getting a handle on where you are in photography.
The last print scan you have shown is really quite good, in fact nothing basically wrong with it at all. There is one minor issue though, I seem to see on my (un-calibrated) monitor a very slight magenta cast. When I look at the footpath stones I see a warmth I usually don't associate with them. Perhaps the background sandstone around the door may give a clue as to whether or not there is a very slight cast. The bright dresses may be influencing the colour of the stones, but I'm not totally convinced.
1 unit of magenta can, and normally does have an influence, when a print is virtually spot on regarding colour and density.
I'm not sure about your darkroom technique, but my method is to contact print every roll or sheet of film. With a colour contact sheet, you will see pretty much the same as a B&W contact sheet, except you don't really have the possibility of lowering the contrast for the contact to see shadow detail.
Once armed with a set of contact sheets, and you have correct colour, you will be amazed at how quickly you are able to print.
You will not need a colour analyser, although they can be quite handy for spot readings of the bride's forehead for when you switch from external pictures to internal with either mixed lighting or total flash pictures.
About the best and cheapest accessory in the colour darkroom is the Ilford enlarging meter, you can of course have quite expensive ones but it will do the job perfectly for change of enlargement factors.
With a change of enlargement the technique I use is simple. First I assume I have a correctly exposed print, but wish to enlarge and crop, either a smidgin, or enormously. I turn all lights off, pull the neg carrier half out, switch the enlarger on, then null the meter under the white light, except it isn't white as you leave the filtration in place. Replace the neg carrier, move the head and neg up for the new enlargement (or reduction) do a rough focus by eye. Then pull the neg carrier half out, place the Ilford meter underneath and switch the enlarger on again. One simply turns the aperture ring until the meter is nulled, bingo, the paper is once again getting exactly the same amount of light. Put the carrier back in, fine focus, then print away.
I used to rotary process all of my colour paper, but I purchased a Durst Printo when RA4 appeared, this unit or ones like it, are quite brilliant. Combined with a B&W RC Rowi paper dryer, I can have a dry to dry RA4 test print in my hot little hand in about 3 1/2 minutes, (the wash is brief and that is being polite).
Providing you are not going to do a zillion weddings, or like shoots, doing the whole lot yourself is quite doable, quite easy, and, most of all, quite satisfying.
If you are looking for a colour analyser, think about the Jobo Colorstar units, they are the only ones I know of that measure all three colour channels at once.
I have the original Colorstar 1000 it will do virtually anything you require, once you have shown it correct colour
