Justin Buzzard interviews Graeme Goldsworthy on his blog. Graeme Goldsworthy has had a tremendous influence on the development of my own theology-- particularly through his books According to Plan: The Unfolding Revelation of God in the Bible and Preaching the Whole Bible As Christian Scripture: The Application of Biblical Theology to Expository Preaching.
I would commend all of his books to you, and if you're not already familiar with him, Justin's interview is a great place to get started. Read the interview here.
(I was able to pick up the UK edition of Goldsworthy's new book, Gospel-centered Hermeneutics, but haven't had a chance to read a page of it yet.)
