The good thing is that you've chosen two sports with similar needs (softball and golf) so you can just focus on the training aspects.
To put things simply. Train somewhat lighter and faster with your upper body exercises. Absorbing the momentum will improve your tendons' abilities to absorb and release force. That improves speed qualities for swinging a club or bat and throwing. Instead of counting reps, use time. Take about 60% of your best weight for exercises like rows, presses, Cable woodchops, etc. and perform them at a higher rate of speed for 20-40 seconds.
Trunk exercises...emphasize isometric holds at the contracted and stretch positions. Again start with time as the control. 20-40 seconds of total isometric time. As you get used to it, you can begin to "bounce" at end range of motion. The goal here is to activate stretch reflexes and improve the muscles stiffness. This again will improve tendon function and increase speed. You can do the same for the shoulders when performing internal and external rotation exercises.
As far as lower body is concerned, you should still perform some regular, progressive, strength-oriented training, squats, deadlift variations, Oly variations (if you know how to do them), Hypers (use the same isometric to oscillating isometric progress like trunk exercises), etc.
Don't totally ignore strength oriented training for any part of the body as you still want to maintain your ability to produce force. To make the adjustments for speed activities, just work you way into the "new" stuff gradually. Going too fast will tear you up.
If you have more questions about specific aspects, just let me know.
