While I don't have a detailed pipe network longsection that would help you, there are some samples you could check out in the tutorial folder that come with civil 3d.
In regard to setting up profile views, search this forum for "House of Style". The search will turn up a PDF document that James Wedding presented at Autodesk University a few years back that covers profile views and the various styles which really helped me out when I started setting up civil 3d.
Generally, if you can draw it manually, you can setup style to have a profile view appear the same. Sometimes it just takes a bit of work.
