Basement Rough In - not a clue where to start

I have some decent DIY experience with framing, drywall, electrical, etc. However a basement rough in plumbing job is something I've never tackled. Here is a picture of the included rough in pipes as they were put in by the builder (house was built in 2000) labeled with numbers:



Here is what I think everything is:

1) sink or vent?
2) sink or vent?
3) toilet drain
4) shower drain
5) sewage pipe and sewage cleanout

I flush toilets and run sinks and hear stuff draining down #5. The thing that really has me confused is #1 and #2. #2 does go up into the first floor....I can snag a picture of that if necessary. Not sure how I am supposed to cut/route them properly. If any more info is needed I will go ahead and supply whatever I can. Thanks for the initial assistance anyone!

Pipes

#1 looks like it could be water supply for toilet.

Is the center of #4 12" from the wall? What's under the black cover?

Mike (Lawrosa) is really good at this game, but I'll give it my best shot:

1) Sink drain (the vent is close, but should have gone up higher before connecting to #2. Not quite right the way it is now, but easily fixed.)
2) Vent for the toilet/shower and sink
3) Toilet
4) Bath tub. You'll probably see a 1.5" pipe with no trap on it. The black box is to leave space without cement for the tub connection and trap
5) Drain for upstairs fixtures with a cleanout.

I don't quite understand the layout they expect you to use. I'm thinking #1 was supposed to be installed with the stub-out facing to the right (in the pic), so you'd have tub, vanity, toilet next to each other.

As long as the toilet and tub are in the right spots, you have some flexibility in re-running the sink drain and vents.
