Reinstall Questions

I was having a problem with FSX crashing every time I opened the kneeboard and went to the Nav Log. So I ended up uninstalling everything (I was thinking about doing a clean reinstall before this problem cropped up anyway). Now that I have been forced to do so, I have a couple of questions:1) Do I need to install SP1 on top of FSX or can I just go right to Acceleration/SP2? Found the answer - YES2) I have the following add-ons. Would there be a recommended order for reinstalling them: - ASX/X-Graphics - UTX - GEX - FS Genesis Mesh - FS Genesis Landclass - Cloud 9 X-Class USA Landclass - MyTraffic-X 5.1b - Flight 1 Ultimate Airliners MD-803) Any of the above that maybe should not be reinstalled?4) Any features of any of the above that should be turned off in favor of the features offered by another (such as in X-Graphics/UTX/GEX)?
