Welcome to the site.
To get the rear valve cover off, you need to remove the alternator support bracket, just remove the sensor and 2 bolts and it'* off. Also need to remove the MAP sensor bracket, 2 10mm bolts and it'* out of the way. Disconnect the fuel lines and that will also help. Remove the cross brace over the struts.
As for the coolant leak. Is it on the right side of the engine? If so, it'* the coolant elbow. These cost about $5 at a auto parts store. Changing your LIM gaskets would be a good idea. Be sure to use the aluminum gaskets.
