This is my recommendation to you:
ESC: MGM 16018 (I say this ESC over the 125b just because of the heat problem that it tends to have)
BL Motor: Feigao 9XL or 10XL; would you prefer more speed, heat, and less run time or less speed, less heat, and longer run time? (If you can swing it, go for a Neu 1515/2.5d; 1700KV)
LiPo Cells: TrueRC 5s2p 8000mAH pack will work great (There are better out there, but they also come at a price. Many people have had great luck with these TrueRC packs, including me
)
