Does this guy like me?

You know sometimes men can be hard to read. With the details you're giving, it's pretty hard to tell if he's flirting or just being friendly. Not to throw you off but, I honestly don't seem a lot of flirting going on here. Try getting to know him more. Talking to him in person instead of just e-mailing. Why? When you talk via-internet it's hard to understand reactions sometimes. For instance, your "This I gotta see" comment, which by the way I do not find inappropriate at all, nothing to be offended by. All in all, my recommendation is get to know him more, go out for a cup of coffee perhaps and talk a little. Hope this helps!
