No.
First of all, you've got the index and column subidentifiers the wrong
way round (and you've omitted the ifEntry subidentifier).

The OID of an instance of 'ifSpecific' would actually be something
like:
     ifTable.ifEntry.ifSpecific.{rownumber}

But the OID of an instance of 'ifName' is *not*:
    ifTable.ifEntry.ifName.{rownumber}
It is actually
    ifXTable.ifXEntry.ifName.{rownumber}

Yes.

As far as the SNMP protocol is concerned, these two tables are
completely independent.   The linkage between the two is a matter of
semantics, not syntax.   It's up to the agent and management application
to pull these two halves together - the low-level protocol operations
don't care.
