How to align weldments?

Please see the attached Solidworks 09 file; I am tryng to model a simple workbench frame.  I drew a 3d sketch, and started putting in structural members.  As you'll see in the sketch, I need the outer edges of the legs to be flush with the upper frame.  Is there a way to "move" the members or should I have somehow planned for the dimensions when I drew  the 3d sketch?  Please keep in mind this is a '2009' formatted document, so if you post an updated file, please be sure it is NOT in 2010 format!
