A couple of men whose writings you'd find informative:
John Dagg's Manual of Theology and Manual of Church Order
John Gill's Body of Doctrinal Divinity and Body of Practical Divinity
Note that Gill is not always confessional and tends at points toward a nearly hyper-Calvinistic position. That being said, he is insightful.
Boyce is terrific, though a product of his time (i.e., his position on creation is reflective of evangelical answers to Darwinism not yet having been formulated; and his chapter on the atonement qualifies him as a 4 1/2-pointer, not a full-orbed 5-pointer. Then again, so does the Abstract of Principles).
The Coxe/Owen volume, Covenant Theology from Adam to Christ, is a personal favorite. RBAP publishes a great edition with a nice introduction by James Renihan.
A.W. Pink has a volume entitled The Divine Covenants which is worth a look.
Pascal Denault's book The Distinctiveness of Baptist Covenant Theology is very good. The book released about the same time by Greg Nichols, Covenant Theology: A Reformed and Baptistic Perspective, is just not helpful in my opinion.
No disrespect at all intended, but I wouldn't waste time or shelf space on A.H. Strong. Just my $0.02...
Of human writings, I would urge above all else that you study the 1689 Confession and the Baptist Catechism closely. It is an excellent resource.
Grace to you.
