We have kind of nicknamed that grill the "sidewinder" since it is the last Genesis with side controls and burners going left to right (or, if you prefer, E-W). Before you get carried away with ordering parts, look over the cabinet and frame. I really like these grills, but they are notorious for collecting rust on the bottom and back. Then it gets to the frame legs. Now you are looking at extensive rust repair and/or some expensive replacement parts.
If you are fortunate enough to have gotten one that was kept inside and dry, then you have the foundation for an extra nice grill. While many of us are seriously loyal to the older "classic" Genesis grills, at this one offers the traditional Weber burner design in a slightly larger, taller standing and more modern looking design. I hope you can really make it look good. Just do your homework first!
