If it has a green hue, then you've let a fair amount of hop debris into your bottles (or at least the one you opened). It's only 8 days as you say - that stuff will settle out over time. Give it another week and be sure to pour carefully with the rest. In the future you could wrap a (sanitized) fine mesh hop bag or even a piece of nylon women's hose around the end of your racking cane to act as a filter. This will help get cleaner beer into your bottling bucket. Don't draw any big conclusions on the beer yet - hops taste great, the debris does not. It'll settle out in time.
EDIT - As soon as you feel the beer is carbed properly, it'll speed up the settling process to keep the bottles in the fridge. Just be sure it's carbed well first - it won't carb any further in the fridge.
+1 - let it carbonate fully, then store them as cold as possible. The rough taste is from hop material in the beer, it should clear once the beer clears.
