Doing Futher Maths and then choosing modules which you'll find "easiest" isn't really a good indication, but on that basis, I'd do FP1, FP3, S2, D1, D2 and either M2 or S3. I say FP3 because it appears (to me) easier than FP2; at least on the OCR syllabus.
I'm doing FP1, FP2, FP3, M2, S2 and D1 (I did C1-4, M1, S1 at Maths A-level).
