At 2 weeks it is a crap shoot as to whether beer will be carbed. General rule used around here is 3 weeks at 70 F. Sometimes it can take longer.
Cloudy: Could be a couple of things. 1) Some yeast takes a long time to flocculate, or 2) chill haze (if it is clear at room temperature, but cloudy when cold, you have chill haze - doesn't affect taste.
I've never used them, but carbonation drops are just plain sugar. I don't know what the right number to use is. I believe there are a couple of types, and of course they are not standardized, so with 1 type, you use 1 per bottle, and with he other you use 2 or 3 depending on how much carbonation you want. If you say what drops you have (and the size of your bottles), maybe someone can tell you how many you should be using per bottle.
