Yes, TTC only for Magic Kingdom. They have cracked down on people Ubering to the Contemporary and walking. You'd need an ADR at the Wave to be able to do that, as even people with mobile orders for the quick-service restaurant have reported being denied access.
For Magic Kingdom, yes. You'll be dropped off at the TTC. For the other parks, Uber can drop you off near that park's entrance. Just don't arrive before the parking lot opens. Uber won't be allowed in before they allow cars in to park.
