What is the name of a good etcher used before priming...

I wouldn't bother. I'd just use a self-etching rattle-can primer such
as NAPA 7220 unless I was doing a lot of priming, in which case I'd
use VariPrime self-etching 2-part primer.

And lastly I need a place to buy used parts for the Marchetti side x side..

That is a hugely tall order. The Marchettis are essentially hand-
built, and are not exactly thick on the ground. You pretty much have
to either make your own repair parts as provided in FAR §21.303(b)2 or
buy a wreck for the parts.
