Is a "three pipe" system i.e. a two pipe system with reversed return useful? Or should I just stick to a two pipe system (a bit easier)?
Is it necessary to balance a system with TRVs anyway?

Sorry, you've lost me!
Yes! If you want the system to heat up evenly, anyway.
Otherwise, some of the far-flung rads may not get hot until the nearer rooms have got up to temperature and shut their TRVs.
