2001 996 Proper shifting with manual transmission

Transmission and Clutch

Vehicle Information: Year: 2001; Body Type: Cabriolet; Total Mileage: 15,000;

I've read three or four of your answers about shifting the 996 6-speed, and I am pretty much doing what you described - 2000 to 3000 rpm on neighborhood streets (which is a lot of 2nd and 3rd gear driving), shifting at 4 to 5000, depending on traffic and street conditions, and cruising at 3,000 in 5th or 6th, depending on the speed limit.However, I recently drove a 2004 Boxster with tiptronic, and I noticed that Porsche has built it so that, under moderate acceleration like driving on neighborhood streets, it upshifted at 2000 rpm to drop the revs to 1500 in the next gear, so that I was in 4th at 30 mph and 5th (the top gear) at 35 mph. Under hard (freeway conditions) acceleration it shifted around 4-4,500 more like what I am used to.Since the designers seem to have put the shift points in lower on the tiptronic, at least for the Boxster, should I be shifting lower (2 - 2,500 rpm) and running lower (1,500 to 2000) under city driving conditions? BTW - I also noticed that the tiptronic starts in 2nd - I assume this is not recommended for a manual transmission?Second (or third) question - sometimes I never get out of first - in a parking lot for instance. When I go to stop and put in the clutch, the transmission "clunks." It doesn't do this in any other gear, for example when slowing down for a stop light from 2nd or third. Am I putting the clutch in too early in first? As it is, it seems if I wait any longer, the car will stall. Or is there a problem?
