Tire liners are absolutely a bad idea. I don't care about the weight they add, but they have the potential to pinch the tube between their edges and the tire, causing the exact problem they're supposed to prevent.
Mixed feelings about Kevlar tires. I used to do all my riding on Specialized Armadillos, but found that once the rubber started to wear a bit from the center they picked up glass and shards and seemed to puncture as easily as a non-kevlar tire.
I run a knobby on the back and a semi-slick on the front now for all city riding (the front is a lot easier to fix in case of a you-know-what).
