OP should be answering questions in this thread but since he isn't, I'll have a go:

1) When do payouts occur?

I've been waiting on my first payout for a couple (6+) hours.

2) In the top right it says "Estimated Per Payout", Is that in Litecoin or is that in the current coin that its mining (Dogecoin atm)?

It is in the current coin being mined.
