FS2002 and project AI

Well I downloaded the installer and nearly all companies in downloads
I have some questions about traffic
How can I check I all my flights plans so that they will work and won't have problems like , no parking space, airport doesn't exist yet, can't fly or will crash on air as it use same flight plan as another flight, what tool can do this for me?
Can I have both default ms flight plans and project AI?
What is a painkit, RAFCAD and AFCAD?
Can I install multiple PAI files with installer v2?
Does anyone know if there is any fingers in airports?
And ground crew?
that's all for now thx
