pmm on the right

To set your menu on the right and have sub-menus fly out to the left, you'll need to edit the horizontal overlap in the PMM window.

Editing the horizontal overlap

Click the PMM icon or choose Modify - Studio VII - Modify Pop Menu Magic by PVII.

Set the % Horizontal Overlap to 190.

Changing the menu offset

Click OK.

Moving the arrow to the left

To move the arrow to the left side of the menu triggers, you will need to edit the background image properties in the #p7PMnav .p7PMtrg and #p7PMnav .p7PMon rules. You'll need to change the arrow from an East-pointing one to a West-pointing one, and change the background-position from right center to left center.

The revised rules should look like this:
#p7PMnav .p7PMtrg {
background-image:  url(p7pm/img/p7PM_dark_west.gif);
background-repeat: no-repeat;
background-position: left center;
#p7PMnav .p7PMon {
background-position: left center;
