You actually do have a red tipped photinia on the right corner, reaching up for the gutters....
Your lava rock works fine, definitely isn't harming anything, it's just terrible to keep the weeds out of after a period of time.
Ditto on the basketball row trimming. There's no need to keep the variegated euonymous encroaching your sidewalk entryway. Your easiest and least expensive move would be to rip em out, and add a couple of flats of color or some bright perennials like scabiosa and victoria blue salvia mixed with blackeyed susan daisies and new gold lantana.
You might google "hot lips" red salvia, too. It has red and white blooms simultaneously that look like candy canes in the air, with a very tough plant that usually doesn't even die back all the way in the winter.
Just some thoughts,
