I just recently went through a new tank setup. Draw a diagram, plan it out. Even though I changed things the diagram I was given was very helpful. Make sure you do a dry run with everything in place and cut down to size. You might struggle to get the pieces apart again but it will give you a good idea about how much or how little to push in the PVC pieces together. Try to make the return from your sump as straight as possible. I would use flex PVC for the return if you can no eliminate turns. Put valves everywhere so you can isolate individual components/pipes for servicing. The one thing I wish I could have done but didn't was to T off the pump in/out with some flex PVC to drain/suck water into/from a bucket. Would make water changes a whole lot easier to do. Measure, measure, measure before you cut. And last of all, make sure the pieces you are cementing are supposed to go together!
Oh, and I hope this is what you mean by pictures of plumbing:
