I wouldn't know about drastically changing the .obj. I've done some minor changes and then edited a copy of the cr2 to point to the new .obj and it worked fine. Just be sure not to overwrite the original files. As for poseable clothing, it simply means that after you apply a pose to your character you can apply the same pose to the item of clothing and then drag it to fit on your character. This is only good for images. Conformable clothing moves with the figure. But, poseable clothing can be made conformable simply by editing a cr2 (usually the catsuit for the female and tuxedo for the male as they include all the parts). It's not complicated at all you can go to www.poserworld.com and search for a tutorial on cr2 editing.
