Any help would be greatly appreciated!

In your photo, you marked two places with red. The lower one is the anode and YES, it needs to be replaced. That, I think, is what all the previous posts have related to.
Now, the top red mark is adjacent to the pressure relief valve. It DOES NOT need replacement, unless it is not working properly. In short, as long as it's not leaking, and when you pull out or push in on the lever, if water comes out of the hose end of that relief valve, and it snaps shut and stops flowing when you remove your finger, it is OK and you don't need to replace it. Pressure relief valves usually last 15-20 years, often much longer than the porcelain lined tank that the anode rod protects.
So, if the valve works, it's good, just get a new anode rod, wrap the threads with teflon tape and install it for next season. I prefer to store the water heater with the anode installed to keep bugs and dirt out of my hot water next spring. Imagine a mouse taking up residence during the winter ???? UGGG
