a) Well if you look at the wiki

http://wiki.openstreetmap.org/wiki/Australian_Tagging_Guidelines#Unsealed_and_4wd_Roads

This will give you an idea of where to start.

b) Realistically if the track is 4wd_only=yes;recommended for part of 
it, it should be 4wd_only=yes;recommended for it's entire length. 
Unless there is definitely a section that can be accessed by other 
vehicles without having to go through a 4wd_only=yes section.

For example I'd tag a track as below in exactly the way the tags are on 
the appropriate sections this would show that all vehicles can acces the 
section up to the 4wd_only=yes but you need to have 4wd_only from there on.

Start of track - 4wd_only=no - 4wd_only=recommended - 4wd_only=yes - 
4wd_only=no - End of track

This one there is really no point in tagging the center bit as 
4wd_only=no (or no tag) as only 4wd's can access the track anyway.

Start of track - 4wd_only=yes - 4wd_only=recommended - 4wd_only=no - 
4wd_only=yes - End of track.

No need to put it in a relation I'd just tag the individual sections of 
the way with the appropriate 4wd_only tag.

A link to the way you are looking at editing would help us help you as well.
