My rule of thumb is always this when a list of things comes up to fix and I can't do them all right away.
1. What keeps the wheels on and me safe. So suspension related things and brakes.
2. what keeps the car running, this includes engine and drive train. I go in order of what hinders them the most and what can cause more problems by not being fixed.
3. things that bug me. An intake boot crack would go in this category makes and annoying whistle but not usually that savaging to the engine(can be though.)
Just some advice that you can do what you want with but if you cant tell your self when something on the car has been replaced I would replace them in the order I just listed. However it looks like you are doing a great job at keeping up maintenance from what you listed above.
Short suspension horror story.. My friend had a wheel hub going out in his 2001 cummins and ignored it for the better part of a year. lucky I wasn't with him when it went and he slammed off the road into the woods.
