In-Game Troubleshooting
The standard method of tracking down problem mod objects in-game is to use Beta Comments.
For debugging scripts, the OBSE command PrintToConsole is very helpful for giving you a way to see in-game debug messages from your scripts.
If you want to create a serious debug environment for tracking down things you see in the game, you can use a dual-monitor setup with TES4View, OBSE and Pluggy to run TES4View on one screen while playing the game on the other. This setup will track what you're looking at in the game and automatically show you details in TES4View about whatever you currently have in your crosshair. Details here.
You can find some of the same information about things you see in the game using FormID Finder and/or RefScope.
