Firstly, re failed slipstream of sp3 by command line. Have followed as best as I could guess the parameters for the slipstream "integrate" command from the prompt. There is no documentation on microsoft or on google for the 'integrate' command parameters that I could find. If anyone knows the proper parameters, please share it. The text in the upper left of the screen shot is from a post from the guide section of the imgburn website. That user was successful using the "integrate" command. I tried it but got the error as shown in the screenshot, that is: " 'sp3final.exe' is not recognized as an internal or external command, operable program or batch file." Screenshot attached.
Secondly, have posted a another question re failure of slipstream xpsp3 with nlite.
