Basement Bathroom Plumbing

have a roughed in basement bath. I'm adding 2 sinks, shower and toilet. I have a 2" vent stack, 4" stub, and 1 1/2" stub.

Toilet is straightforward, but where should I run the drains for the sink and shower? I was thinking all 3 into the vented 2". Or should I run something into the 1 1/2" and tie the 2" vent into that? Sinks will be almost back to back
on opposite sides of the wall. Is there an easy way to connect drains there?

The 1.5" drain is fine for the sink, but the shower needs a dedicated 2" drain (which can be tied into the 4" toilet drain later on). I'm not sure how the venting requirements go, I know you can vent a toilet using a 2" vent, but I don't know if you can share that vent with something else. Plumbing is not my specialty... wait for a real plumber to give you more information.
It's always a good idea to ask the local building department of their requirements.
