Sewer/Wastewater Geometric Network - Newbie

Hi all, I'm wanting to put my sewer GIS data into a Geometric Network to take advantage of the tracing routines. I have a very large collection system already built in a geodatabase and I have a few questions.
1. In general practices, should service laterals be included as an Simple Edge? So when running a trace upstream it selects any/all service laterals that could be contributing. Or, should service laterals even be included in the network at all?
2. I did a simply Geometric Network test on a copy of my data once and tested the Trace Downstream. I noticed it takes any Path at a manhole structure. I'd like to ensure it takes the correct sewer main when it enters a manhole structure with multiple effluent lines by using the lowest pipe, currently using a downstream invert elevation. Is this possible?
3. Is there any issues checking data out for GPS collection? Do I have to break the network, collect points, check in points, and then re-build the network? I'm using ArcPad.

Any other general practices that I should be aware of?

Thanks in advance
