All sounds normal to me too. The 1st to 2nd shift aught to improve with a warm gearbox, just change slowly whilst cold not beating the syncromesh. The noisy thrust bearing on the clutch is nothing to worry about but TBH I am a little surprised after such few miles, my 350 was a bit that way but that was after several years/mile worth of use. Personally I wouldn't get too concerned....and I would be very hesitant to take it to a garage in any case.
