Shawn,
Based on the number of posts you have been around the block here on PSW a time or two. So the following should be nothing new to you:
First off, go to the Study Hall section and read up whatever you can on system setup, signal flow, gain structure, etc. Another excellent reference is the Yamaha Sound Reinforcement Handbook, considered by many as the bible of basic audio knowledge.
After digesting some of that, make a list of what you have and post it over in the lounge, asking similar questions to what you have asked here. See where you are at that point, and if things aren't a bit clearer you may want to find a fellow labster near your area who can work with you for a day to optimize your setup.
