I need to know if this is normal
When changing gears from 1-2 then 2-3 if change quickly and then step on it the clutch plate slips almost to where the engine is revs up to 5k rpms before catching.
the car has 32k miles does BMW need to adjust the clutch plate?

(notice how I avoid claiming to be an expert?) but there is a restrictive orafice in the clutch line that softens any attempt to "dump" the clutch. I recently changed out my line with a UUC version that does away with this annoyance. My problem was that with 5 years on the line, it was getting spongy enough that on hot days in stop and go traffic that it would flex (expand) against the restriction enough to not fully disengage the clutch preventing my changing gears. This replacement has eliminated this and actually raised the contact point to a more desirable level.
I have had this "slipping" you describe actually make me wonder about a need to replace the clutch. With the new UUC clutch line (and the ever valuable info you find in this forum!), this is no longer a concern.

I have the same problem. It happens more so at higher speeds than at low. I have heard that when you remove this restriction from the line you will no longer have clutch slippage and you wont be smelling clutch smoke every time you step on it!

Yes the clutch is shot!!! 
He also pulled up 6 error codes!
093 O2 sensor after cat
042 Dr=irect speed imput
020 Start relay
019 Secondary airpump replay
057 Airmass sensor
135 Both V-signal sources
Well at least its still under warrantee

I am kinda not following you

May I suggest a technique issue? The revs need to fall a bit prior to engaging the clutch and the clutch needs to be completely engaged prior to getting on the gas again. To do otherwise fries clutches in 30k miles. They should last to 130-160k miles.
Replacing the clutch hose with one without the restriction will speed up the shifting process, but not completely. The only kind of clutches that I know of that can take really really fast shifts for any period of time are the 5.5" race clutchs that are good for huge torque. But they are on/off switches with no ability to slip.
