Welcome aboard Wes!
You can get cleats on Amazon or at boating retailers like West Marine. There are different sizes and styles though. Be sure to put some putty in the screw holes so the new cleat mounting screws are in solid.
Where was the kink in the lower shift cable? Are you talking the metal cable itself, the jacket, or both?
Water in the bilge is a concern and you need to locate the source. Bellows replacement as Mike suggested is a good idea. You can test for leaks by putting the boat in the water and watching to see if the bilge gets water. If no water coming in just sitting then start the engine and check the bilge again. Leak could be bellows or cooling system. You may have no leak at all however, and the bilge water is from people dripping water in the boat. Make sure your bilge pump works.
You also mention a lean. Weight distribution is an art form in an 18 ft boat. Is your anchor and battery on the port side? Does the boat list to either side when sitting the water unloaded?
