What costs does Ezreal, Prodigy reduce? Does he reduce Repeat costs? Accelerate costs? Equip costs?

Ezreal reduces optional additional costs using both "additional cost" and "may." Repeat and Accelerate qualify, but not Equip costs - that's an activation cost for an ability, so it's neither optional nor additional.

What parts of a spell does the Repeat ability cause to be repeated? Is it the entire effect? If I use Temporal Portal to give Find Your Center Repeat and pay the cost while its cost reduction applies, does the cost reduction happen once or twice, and does the final spell cost 2 or 4?

Repeat causes repetition of a spell's instructions. Find Your Center's cost reduction applies once, making the final cost 4 - its base cost of 3, plus its Repeat cost of 3, minus its cost reduction of 2.
