I believe the answer to both questions is yes.

In order for OTV to function without jumbo frame support across the WAN you should reduce the MTU of any device which needs to send traffic via OTV in order to accommodate the 42-byte OTV header.  OTV doesn't support fragmentation on the Nexus 7k, for example.

1) Can OTV work in within a complete unicast environment?
Yes. That's been available since version 5.2

2) Can OTV function without jumbo frame capability within the WAN.
Yes, like Craig said, you'll lose 42 bytes.
