Okay, that explanation and picture help a lot. So first a quick tip. When you import the .OBJ file, I wouldn't bother clicking on Centered, that's probably what's putting it in the middle of the floor. It'll just save you some translation steps if you don't, but it's not a big deal.
Next, you can't conform a prop in Poser, which is what you're jumpsuit is when you bring it in as an OBJ file. Poser actually thinks you are trying to conform Dawn to some other figure. In Poser you sort of always have both a Figure and a Prop selected at the same time (assuming you have a figure in your scene). Figures in Poser have skeletons, but they are made up of a series of props, so Dawn's hand is basically a prop part of Dawn (at least that's the way I think of it).
I edited this image to maybe help explain:
So here's what you need to do to make the jumpsuit a conforming figure. Once you have it positioned and called correctly, go to the fitting room. I wouldn't worry about poke through yet because one of the things the fitting room does is try and take care of that for you.
Like I said before, don't zero the jumpsuit if you have made any changes to it's scale or translation. Once you've run a fit in the fitting room, you now need to click the Create Figure button in the fitting room. After you give a name to the new Figure you are creating, you'll get a window like this:
You'll want to uncheck Dawn's Head, Hands, and Feet and all their subparts.
Now, if you've already done grouping in another program, you'll want to uncheck auto group, otherwise leave it checked. You can click the Select button if you want to choose what Dawn morphs are brought over, or you can leave them all (I'm not sure what's on the Dev Rig) and do keep Zero Rotations clicked.
Once that is done, go back to the Pose room. You're actually gong to have two versions of your jumpsuit in the scene now. The original prop one, and a second figure that you just made. For now hide the original one, because you may find you need to redo something that went wrong in the fitting. Now select the Figure you made, and you should be able to Conform it to Dawn the same way you were trying before. Second with the new Jumpsuit Figure selected, go up to the Figure menu and choose Copy Joint Zones From . . . and copy of Dawn's joint zones (this basically gives you her weight mapping as a place to start). At the point you should be able to play around and figure out what needs to be adjusted/fixed.
Hope that helps.
