I didn't mean to discourage you too too much from asking, but part of the LF ethos is "do it yourself" and that includes seeking information. There's a lot out there, in fact there's a lot right here on APUG, that's not too hard to find. There are, though, some questions, mainly having to do with less common gear, that haven't been answered yet. Search first, then ask.
its just that zeiss has made a lot of planars and i still dont know how and why each one is different. For instance are the planars made for graflex xls lower quality than ones in linhof shutters? I know that linhof supposedly throes out half the lenses they get but aren't zeiss lenses supposed to be really good before linhof throws half of them away? I think that linhof used some zeiss lenses, atleast i have found some technika kits equipped with a biogon and a planar and a tele-arton.
Planars are excellent lenses, as are Xenotars. If your primary concern is speed for handheld and low light photography with a 6x9 Technika, and movements aren't a priority, these are the lenses to look for.
If you want a sharp lens with more coverage to use movements, you sacrifice speed, and look for a modern plasmat like a Symmar or Sironar.
It's not a bad idea to have a mix of lenses so you can do both things.
