Ladies Only Please: Serious Dating Advice Needed For A Love-shy Guy?

http://en.wikipedia.org/wiki/Love-shy – this essentially describes my current situation with women. At age 30 and despite many professional successes and being told I’m a very nice and caring person by many people, I have never had a g/f or been in a relationship (ever).
To try to fix the relationship situation, and b/c repeated efforts at online dating just didn’t work for me, I signed up for a local brick-and-mortar matchmaking service that tries to match people looking for serious and long-term relationships, with the ultimate goal of matching people with persons that would make good potential partners for an eventual married relationship. Criteria used to match are based on compatibility, numerous scientific personality assessments, and other character assessments. I am guaranteed nearly 30 unique matches for potential dates, which the agency coordinates.
So the first match arrived by postal mail today, with the a summary of the match’s interests, profile, and phone number included. To set up the actual date, I have to call the match to ask her out and take it from there to see how things go. However, given the approach being used and my inexperience with relationships, what would you recommend actually talking about with the match on the first phone call? Also any recommendations on what would be a good first date idea? Thanks!
