My 2 cents worth in addition to what others have suggested:
Make sure inserts are flush to the table top - I have been hurt by this one.
I would not use metal push sticks. Aluminum comes to mind, but it is metal, and I am feaful of it. I can see it getting thrown at me.
Do not use damaged push sticks
If a sleds, jig or rig is damaged or isn't working right, fix it before using it - I have been hurt by this one. Oak runner had swelled up.
I believe in guards, but I too forego the blade guard. I do have a riving knife, and do believe in using it or a splitter to aid in limiting the possibility of a kickback. A Sawstop is a very neat machine and can prevent many accidents, but the saw can still kick back or throw a board and hurt you.
Keep the junk off the saw. Too many times I leave too much other stuff (boards, tools, rulers, etc) on the saw that cause clutter and obstructions. This is one that I really need to do better.
And remember this from Nahm. There is no more important safety rule that to wear these, safety glasses.
I wear glasses, and my lenses are plastic and shatter proof. They have saved me from what could have been bad twice.
