the four holes on rear are for wall mounted bracket, the stand that goes in bottom generally requires the removing of a cover plate which will be about size of the upper part of stand and will be approx four screws, remove cover and stand will slot in and fix with scres/bolts accordingly.

Here is the back of your panel. As you can see you have 2 HDMI inputs. Good luck!

Just purchase a mount for 42" and above They come in different styles for your likening and make sure the wall bracket gets mounted into the wall studs and your all set. No major job. I get $150 all day long for those installs.

just need the right cable. Look into getting a VGA-HDMI cable

The screw holes are metric. The set is supplied with M5x25 screws to attach the pedestal, so the wall mount screws will be in that same range.

I am not familar with your exact model but my Panasonic TH-42PX600U 42 in. Plasma uses a generic brand wall mount. The first mount I bought would not fit so I returned it and bought a different brand which worked well. Start shopping your local stores (even walmart has a couple of different types to choose from), carefully open the packaging in case you need to return it and see if it will fit the mounting holes on the back of your TV. If it fits on the back of the TV then you should be good to go.
