It could very well be the if-index but it doesn’t have to me. It is whatever the neighbor choses to use to uniquely identify its interfaces. Excerpted from RFC 5340, Appendix A.3.2:


   Interface ID
      32-bit number uniquely identifying this interface among the
      collection of this router's interfaces.  For example, in some
      implementations it may be possible to use the MIB-II IfIndex
      ([INTFMIB]).


> - Should leaf metric be of type ospf-metric or ospf-leaf-metric instead of uint16?

The 24 bit metrics should be ospf:ospf-metric. The 16-bit metric should be ospf:ospf-link-metric. I’ll update these in the next revision.  

Thanks,
Acee
