In Photoshop Elements, select "rotate" in the "image" portion of the toolbar, and then "custom" within "rotate", specifying the number of degrees, and direction (right or left) that it looks like it would take to get the shot level. It's possible to use fractional degrees (0.5 or 1.7, for example) although that may be more fine-tuning than necessary. It may take several tries to get the image where you want it, and then you will need to re-crop, since the overall image has been tilted.
As for "grid", this places a cross-hatched (vertical/horizontal) pattern across the image which can be used to check for perpendicular horizon or verticals. Accessed in PS Elements via the "view" portion of the toolbar, and toggles on/off.
Hope this is helpful.

Yeah, that shot doesn't look objectionably unlevel, does it?
So how do you check it once you've got the grid? If you can assume those lines on the terminal are in fact vertical, then you align the one at the center of the frame with the grid. Remember, if the lens axis is pointed below the horizon the vertical lines don't appear parallel on the image-- but if a vertical line at the center of the frame is perpendicular to the top edge of the frame then I guess that makes the camera "level", by definition.

In the PS CS toolbar keep the eyedropper button pressed until you get two more options and then select the MEASURE TOOL,then drag the pointer over a line/pole/whatever that should be completely vertical in your photo. Now rotate the image Arbitrarily and will see that the degrees field hasalready been filled.

Yes, all the vertical lines in the photo should be as vertical as possible. Sometimes the outter vertical lines lean inwards (depends on the lens) but that doesn't seem to be a problem with this photo. Just rotate it CCW a bit.
