i do not have any experience with printing low-res images, so i'd rather ask. I did a kid's birthday party today. I want to give out a CD with all pictures to let parents post pictures on the Web or print 4x6 (but not 8x10 due to lack of IQ), as i want to keep all rights to print larger sized posters, etc if anyone wants them. To what resolution should i resize images for the CD?

I agree with Barry's splitting hairs comment. But personally I would recommend a resolution between JRP and Barry ( but closer to Barry).
For my personal preference I would not print below 150 PPI. So for a 4x6 print that would work out to a resolution of 600x900. That size would be good for web posting, and a decent quality 4x6. But a less then quality 8x10 at about 75 PPI.
I feel that Barry's 100 PPI for a 4x6 print to low, and JRP's 300 to 360 for a 4x6 would still allow a decent quality 8x10 at 150 to 180 PPI.
Most mini-labs print at a default/native resolution of 300 ppi. If you are concerned that someone is going to take their CD to the local Sam's Club and succumb to the temptation and upsize a few images to 8x10 then you could reduce the resolution of the 4x6 images to 150 ppi. The parents will hardly notice any reduced quality on a 4x6 sized print.
