Photoshop :: Group/Layer Auto-sizing

My problem: Because I deal with a lot of layers and groups I always strive to find some easier way to manage them and one of the things I always struggle with is getting everything in one group to stay a certain width or height, especially text.

Desired Solution: I combine each section, such as all the elements for the left column, in its own group and label it accordingly (A life saver when trying to find and edit something ). Then when I add an element to a group I would like the predefined width restriction applied to it so that no content can extend outside that area even if I take my text tool and select the entire document.

Is there any way to do this? Right now I'm stuck with using vibrant group backgrounds with the desired width or height as a guide. This isn't too bad a solution but can sometimes be time consuming, especially if there's a lot of content. If this is possible is there also some way to apply a padding to it?
