I'd mostly leave it as is and put my effort into riding/training with it.
OP lives in Indiana, may want/need decent full fenders. I've had
these VO fenders on my 26" bike for about a decade/35,000 miles, they are still in good shape, highly recommended.
For racks and fenders I recommend Tubus and Ortlieb. Tubus Cargo and Tara racks fit Truckers very well.
