Hello pdp I can't say anything about the CFL's I've never used them but if they produce red light they should be fine.
The MH will flower alone but I've heard that around a 10% reduction in bud can be expected compared to using a HPS bulb.

I was forced to use a MH for a long time on the flowering of my last grow and I noticed that the buds were less compact/dense. However it did produce bud.

Sorry I can't tell you anymore
