Am i crazy?

No you're not crazy. This is an ongoing thing and always will be. Besides: you don't want to make it so perfect you'll be afraid to drive it, nor do you want to tear it all down with some grand plan, then realize you've taken on too much. Fix what needs fixing, drive it, enjoy it, make improvements within your budget. You'll find getting small things done almost as satisfying as making big changes.
That's a fine looking rig. Good start, solid foundation. You may have found a friend for life.
