Andrew is a really cute choice! Neither of your first names are my style since I don't really care for surnames as first names unless they have family significance. I'd probably choose Brooks for the first name but the pp's suggestion of Andrew Jameson is really a strong name for a man.
I know Brooks is all boy but I always think of Brooke so it rings feminine to me. Not a huge fan of Jameson either. I agree with PPs and would go with Andrew.
I live the name Brooks. Jameson is a move sounding name, but it is pretty popular right now (I have two friends that are naming their boys this) and it's the name of an alcohol.

Jameson is ok but I'd switch them around like pps have suggested.
