Okay….
after litteraly over a dozen tries, I FINALLY got the proper settings and proceedures for importing objects from Poser to Carrara, doing the work to make the morphs I need, and exporting the result in a way that won’t mess up when used in Poser!
Admins! You guys might ought to sticky THIS post! I’m sure it’ll come in handy for others having much the same issues as I’ve had
When we open Carrara, there are several options for getting .obj figures into the program….but THIS ONE combo works! (there may be other option combinations, but having found this one, sorry, but I’m not looking beyond WHAT WORKS NOW!)
You want to know what I found?
Do you really want to know?
Have I teased you all enough yet? 
Okay…
Here’s the situation: You have an idea for a morph you want to create for a figure for use in Poser. Only problem is, Carrara isn’t really nice about letting you make one that you can use in Poser! After you’ve made your morph & saved it, you all too often find to your dismay that when you try using it in Poser, the target morph suddenly makes the body part or figure become gargantuen and/or tiny. (& YES, once, both happened to one of my efforts…the results—were NOT pretty!
)
The Solution:
When you open Carrara, you get the blank field where you have the option of creating a new workplace or opening a preexisting work.
1) Use OPEN...with the explorer list, navigate to the location of the Geometry where your figure is located. Select the *.obj file you want. Don’t use a NEW SCENE (whatever the 3 optional sizes) & Import the figure, it’ll mess up your efforts!
2) NOW THIS IS IMPORTANT! In the options for opening the file, select “POSER” from the dropdown menu. DON’T use Default! It’ll mess up your work!!
3) ANOTHER THING THAT’S IMPORTANT!! When you have selected “Poser”, several other options will automatically set themselves—-one of which is SCALE (1 Carrara unit = 96.00 Poser units)——SET THIS BACK TO “1.00”!! (& DON’T trust Default’s setting as =1.00, it doesn’t work!!)
4) Use Vertex Modeler with “Create One Object”—this is not so much important, but chances are, you’re already been using this to modify your figures. If all is good, that should not have changed. You should be good to import now…
5) Make your desired changes to the figure. If it’s a brand new, full-body change or a morph target for a specific body part, you know the routine by now…
6) NOW THIS IS IMPORTANT AGAIN! VERY IMPORTANT!! Now, when you’re ready to save your figure (either from being finished or needing to go to the bathroom/kitchen/bed/place-of-employment/etc), you need to save your work. Use “DEFAULT” for the save setting in the dropdown menu! DON’T use “Poser” here, it WILL mess up all that hard work you’ve just accomplished!!!
7) Save your newly modified figure—BTW, not so much important, but it does help to remember where you put it….but chances are, you’re brain is pretty well fried from all the previous efforts to make a new figure that Carrara’s other various save options have so helpfully ruined, so making an effort to recall the location of the new file might be useful to recovering some portion of your sanity….
8) Repeat the above steps if you need to come back to your work (if Step 6 was done because your modifications were interrupted) OR you can proceed to Poser, import your figure/morph target...& voila!...SUCCESS!!!! 
9) Now, got to your psycharatrist/mental-health-professional with samples of your work as documented proof THAT IT IS POSSIBLE TO MAKE A MORPH FOR A POSER FIGURE USING CARRARA, screaming “YES, I CAN!!” He’ll either think you’re an Obama supporter & have you committed for life, OR he’ll see the work, realize you’ve been telling the truth all along, & stamp your file “CURED!”*
*—This is no guarantee of which of the two quantum states will result from the decission of your mental-health professional. Your actual results may vary.
(BTW, this post is intended to provide useful information on the issues between Carrara and Poser, and not intended to give or cause offense resulting from any political references…as stated in the disclaimer, “Your actual results may vary”—you might still get committed even if your mental health care provider understands you’ve been telling the truth about making morphs with Carrara….)

I hope that this post will help someone else out there, who, like me, is not an expert in dealing with these programs. It’s been quite frustrating to me that I couldn’t find such information burried either in the old forum or here.
