I ALWAYS answer these. I'm just late.
Mod conflicts should always be pretty apparant, like two different things modding the same object, like a creature. It's always good to install one mod at a time and test them individually along with the rest of your pre-installed mods. You're really in trouble if it's several days after you discover a glitch and have installed many mods thereafter. I don't use OBMM so I wouldn't really know about how to use it to diagnose a problem. You could examine the situation where it's giving you conflict. I'll use one situation I had for example. I had recenly installed MoDem's City Life, and went around doing the main quest with the Blades. It was the part where you had to kill the spies near the runestone at dusk. Two of MoDem's added "Town Militia" characters from Bruma came out and helped me do battle. Afterwards, they attacked me (I accidentally stabbed them... twice) and I killed them. I went back into Bruma via the North Gate, did some buisness, then left the town via the East gate. When loaded, the game crashed. Looking back and remembering the characters that died, I uninstalled City Life, and the game kept running smoothly.
By the way, let me know if the Landscapes mod runs well with the original quest and such when you're done with it, I'm being wary.
On keeping your Data folder organized, I like to tell the folder to categorize the files by type, and give a different standard icon for each.
That should pretty much cover everything I know.
