1) Is there any way to output serial from pins 2-13? Or PWM from 2,11,12? Or stick a potentiometer to 4-12? Cos the hardware information from the main website say this "In addition, some pins have specialized functions"
2) Does sending PWM to 6 servos make the Arduino lag, or can it multitask? (because the BASIC stamp code I wrote did 1.5ms of servo 1, 1.5ms of servo 2, etc, so it added up to quite a bit of lag)
Thanks!

Yes, you can use the software serial libraries on pins 2-13. No, unless you drive the PWM yourself in software. No, you can't put pots on pins 4-12.

Use the MegaServo libraries.
The Arduino's performance is very much faster than the BasicStamp's.
thanks i love you. i wish i could download your stuff into my brain. can you make an ardie for that? 
thanks again mate.
