It seems you've had problems with maintaining the image size and not cropping the logo. However, there's a fix. This is my recommendation. You don't need to have items broken up into layers to make adjustments.
First select your
POLYGONAL LASSO and outline the logo. Make sure
BLACK is selected as the background color.

Second, select
FREE TRANSFORM and re-size the logo.

Now, there will be a little bit of clean up but it should be pretty easy. You should now be able to position the art work without the logo spilling outside the border.
