There are a lot of people posting in this thread that aren't giving the best advice...Don't use any snap to anything, don't use beat detective, do it by hand. Cut, drag, crossfade, cut, drag, crossfade. If you don't crossfade, there will be pops and clicks on all of your slices. You shouldn't really be using any time stretching technique (that's elastic audio right?) unless you have to...it sounds weird. Maybe you might want to take a look at AdamWathan's slip editing video to understand the concept, even if it may not apply directly to your DAW.
