It's POS like NXT - no block rewards, just fees for forgers. You need 1000 XEL to start forging.
And pro day you have ?
It depends on the fees in the blocks. Not much for now, since not too many transactions in the network. You can check block explorer here http://elasticexplorer.org/ - the majority of blocks are empty.
Also the situation is going to change when the main features launch. Then job submitters will pay to people renting CPU and GPU power. All on blockchain. XEL is AWESOME.
