*sigh* Gave name to probable scammer - should I be worried?

I just put my apartment (university town in the Midwestern US) up on craigslist yesterday, and I got a reply last night at about 5 AM:

<url of my ad>
Hi,
I 'm interested in the sublet space/share room you advertised on craigslist.org and I would love to know if that's the actual price per month and the date of its availability? Pls let me know if there are any changes.
Hope the space is cool and environmental friendly.
Thanks

This seemed a bit fishy, so I checked the email header, which was from an IP in Ireland. But I thought there was an off chance it might just be a foreign student (lot of foreign graduate students here), so I sent a non-committal reply and was careful to not include any personal info. However, Google included my name with my email address in the "To" field, so now this person's got my name (NOT my address, phone number, or anything else - I didn't put those in the ad). Is there anything I should be worried about?

EDIT: It's definitely a scam, I got a follow-up that asked for my full name and address because their boss would be paying for everything, etc. The email address is [email protected].

If you cut off communication now, and all he has is your name, you have nothing to worry about. If you're using Gmail on the web, he doesn't even have your IP address.
