speculatively sent CV out - had a little interest - now what?

Okay so here's the deal:

The CV + cover letters I speculatively sent out to various boutique IB's during the last couple of weeks have, at last, received a bit of positive attention.
One 'head of research' (more of an economist/strategist) is "interested" by my CV and suggested a meeting to find out more - although he concedes he has no specific opening in mind.

To put in context, after graduating from uni & passing CFA level 1, I have been working for a major company in the financial services sector (albeit not IB, and not equities related) - but I'm very keen to make the move to equity research.

Basically, I am seeking advice as to how best to equip myself for the meeting. Speculatively sending CV's is unlikely to yield many more small windows of opportunites for me, so I ought to prepare as thoroughly as possible.

For a start, I suppose jogging my memory on some of the most significant CFA topics, eg DCF, would be a wise move, but in what other directions should I focus my attention?

Bah - apologies for the vague nature of the post - I would have given more information if I had any... I'm just somewhat anxious to capitalize on the line I've been thrown.

Many thanks for thoughts on the matter.
