Salaam,
When offering ‘qaza namaz’ for a ‘salat-ul-Isha’ do I have to pray only 4 ‘farz’ or also offer 3 ‘witar’? Also, are witar in salat-ul-Isha farz, wajib or sunnat? Thanks.
witr are wajib.
PS. I’ve always wanted to know what’s the difference betwenn Farz and Wajib? 
There are two kinds of FARZ
(i) FARZ-E-AIN
(ii) FARZ KIFAYA
(i) FARZ-E-AIN
The Farz which is obligatory to be accomplished by every adult and sane person. One who misses it without any reason is a grave sinner (Fasiq).
(ii) FARZ-E- KIFAYA
The Farz which , if accomplished by some persons relieves others from its responsibilities, but non- accomplishment by anyone renders all as sinners.
(2) WAJIB (Essential)
The command which is based on presumptive arguments and there is difference of opinion or doubt about its having conclusive evidence. One who denies it is not a Kafir but of course, the one who misses it without any valid reason is a Fasiq, and is due for punishment.

Re: Isha qaza namaz
You should also offer witars. You even cannot skip them in Qasr namaz. As the other brothers mentioned, witar are wajib.
