It seems the most common VW gas inline engine is a 2.0 block with 1.8
8V head. Doing this on a 2.1 WBX Vanagon allows one to keep some of
the 2.1 parts. (air cleaner etc.) With Digijet, how many, if any,
components could one keep? Air cleaner? AFM? FP, ECU relays?

Engine mounted inline with vehicle is all I've ever seen. A transverse
mount would require some serious fabrication. Not sure why someone
would attempt this!      ;)

You will get varying opinions on which engine management is best. eg.
some (few?) swear by CIS. Digifant is pretty common. I'm running
Motronic (as c/w the engine I installed)

Installing a "stock" 2.0 means lowering the drivetrain a fair amount
to avoid having a bump in the engine lid from the "crossflow" intake
manifold. This is why most use the 1.8 8V head. It has a "counterflow"
intake which puts it on the low side of the engine, engine mounted @
50º

Here's a page I put together with links to various related projects:
