Our friend's 1.67GHz G4 powerbook has been experiencing sluggish performance. We have done PRAM and disk repair. What else can we try? Tia

Run activity monitor, see if something is taking a large percentage of the CPU time. Try to find a cause before applying random solutions.

Ditto above. And empty the trash. Hey, it couldn't hurt.

Do a safe-boot.
Restart with the shift key held down. Continue to hold it until the swirly appears under the Apple logo. Restart at your earliest opportunity.

When I had that same problem, it turned out that one memory chip had failed.
Go to System Profiler and see how much memory is showing. Run a memory test.

Actually, it was not the chip that failed on my PB. It was the lower chip socket, the one closest to the motherboard.
