I'd hold off on all tweaks for awhile. Win7 doesn't need tweaking, and an 11 second startup isn't to be messed with considering what you had all day today.
Stick with the drivers given by Win7 installer, then quickly updated via optional Windows Updates. Install those optional Update drivers first to see if any affect startup. Then enable hardware driver auto-updating: Automatically get recommended drivers and updates for your hardware
Break your other Updates into smaller groups starting with Security Updates, then monitor performance (espcially Startup) after each Update group, program install, etc.through several startups to see what might be problematic.
When you have a performance hit or Startup delay, System Restore to before the last install done and reinstall everything in that group singly to determine the exact driver or program causing issue.
Monitor the logs all along: Computer lags every couple seconds
