i would need a screenshot now.
i guess the main part of the site has the correct width now while the top and bottom parts still are too wide.

this has two possible solutions:

1) go to your style options, click fonts/colors/etc and change your Content Table Width to 730, which should change your overall layout.

2) go to your options table, go to the templates ection of it and switch the option "Add template name in comments" to yes.
afterwards reload your private message view, and take a look in the sourcecode. youll find now the template names as comments in the source. you will notice that some other templates are in that view too, for example the header and usercp_nav. you have to make sure then that the table-widthes in all these templates are corredtly set to 730.

if your problem is differerent i would new need new screenshots of your different private message screens.

btw, your templates that you attached are ok.

greets
