Can network analyst actually do anything, instead of just trace?

After some lengthy manipulations I've managed to establish a pretty neat network using Network Analyst for ArcGIS 10.0.

I do have some issues though, mainly,

The outpoint I established from each basin is not always recognized when using network solvers. Even though I got my arrows to work, pointing towards to the outpoint location of each basin, when I place a flag on an outpoint and select Trace Upstream some outpoints will only select themselves. However, when I click on a nearby network_junction the trace works fine. Any suggestions on this? Also, do I manually have to flag every point I want to perform a task on?

The other issue is can this network actually do anything aside from just trace?
I have a number of polygon basins that I am trying to connect with each other so that the value of one basin upstream is added to the one downstream until it reaches a final discharge point. The end goal is to have each basin symbolized by this value.  I've spent days and days getting this network and I am worried that it might have been all in vain!

Any suggestions here? I would assume there is some way where each basin's outpoint value can obtain values from upstream outpoint, which then could be joined to that outpoints area.
