I've never seen a street union. They might exist...
You don't need a piece between union and wye if you have a street wye.
But I'd use a rubber coupler, or a rubber wye. It makes it easier to
get everything lined up if the pump isn't exactly in the right spot.
But then I also wouldn't worry about an extra joint or two. A
properly solvent welded joint is pretty darn close to a solid piece
of pipe.
