[Andy Zou] “This is obviously a very broad, contextual question, but is there a good rule of thumb for how often to pre-compose? Especially when elements are involved that will be used in multiple compositions?”
I’d argue that if you have a common element that will be re-used across multiple comps, you should precompose it and do all your work inside that precomp. That way, you KNOW that any changes you make will correctly ripple across the project.
[Andy Zou] “If in premiere I have dozens of clips from one take being used in different spots, should I replace each clip with its own precomposition in AE? Or, should I make one master comp from the original take so I don’t have to redo the same key/effect on all dozen clips, and especially if I have to change anything?”
Having to keep multiple effects in sync manually across a project sounds like a recipe for errors. This is the perfect case for precomps, or perhaps for property links:

One of my favorite hidden little features in Ae is the ability to precompose an item from the project panel. For example, if you already have a piece of footage used in 19 different comps, you can right-click that footage item in the project panel and choose “Replace with Precomp (used x times).” This will create a simple precomp that contains the item, and replace every single use of the item throughout the project with that precomp. It’s very helpful for making a precomp sometime when you didn’t plan it ahead of time.
