EOC on the highway, some questions

I've been getting a little bolder about EOC, i recently started doing it on a couple good spots on the highway. What I normally do is get up to 60 (keeping my instant MPG >35-40), turn the engine off, coast (in neutral) down to about 52, and bump start into 5th gear

1) is this hurting my car? is there a better way to do it? should I not be doing EOC at those higher speeds?

2) I just read another thread about messing up an engine if doing EOC by shutting off the engine.....is this an issue with newer cars (ergo, my '09 cobalt?) I gathered that I should be letting the engine drop to idle before turning off the engine...is that enough?
