When I bought my MBP 2.2 GHZ in 2007, it got from dead to an active dock in about 18 seconds, and now it takes about 1:30 to get a fully responsive home screen.

I want to find a way to profile the various things it does when it starts up so I can begin tuning it a bit.

Any good software or other recommendations for this process?

I recommend you start by browsing the /var/log/system.log messages from the times of the last couple boots and see if anything jumps out at you. Then reboot and immediately hold down Cmd-V (verbose boot) at boot time and see what gets logged to the screen immediately before and immediately after any long pauses.

Let us know what you find.

Profiling? No. Finding out what kind of junk you've got installed that's running itself when you aren't looking, yes:
