I don't even know where to begin.....
First off using the Alcohol scale on a triple scale hydrometer is not accurate for beer, especially if you just started fermentation..they way you calculate ABV is by taking a grav reading before you pitch the yeast (OG)....then one after fermentation has stopped and the hydrometer reading stayed the same for 3 days... that is the final gravity reading..(FG)
The formula for ABV is OG - Fg X 131
Your beer is not 2%, you read the wrong scale.
This is the scale to read...
If you brewed a kit OR followed a proven recipe then your ABV is around whatever the recipe says it is...
NEXT
The dirt floating on it is called Krauzen, it means fermentation is happenning and it will fall and eventually clear, actually it is probably the remainder of the krauzen...it is normal it will fall.
It is a sign that fermentation is occuring/occured NORMALLY!
Thirdly
The beer will taste flat until you bottle it and let it carb and condition for 3 weeks at 70 degrees.
Fourthly
Bubbling of an airlock really means nothing, it is not an indication of fermentation, there are too many factors that affect bubbling of an airlock, including the seal around the carboy or bucket, or too many co2 bubbles sitting on the bell valve...The only way to tell is with the
proper hydrometer readings as mentioned in the beginning.
AND
It tasting like Redstripe or anything at this phase means nothing...The beer is Green and Raw...
Again this has to do with the lack of carbonation/bottle conditioning.

DON'T ADD ANYTHING ELSE TO THE BEER OR MOVE, IT EVERYTHING IS FINE!!!!
Everything you described is normal...
You just have n00bitus!!!!!!!
Leave it till thursday, take a hydro reading, then again on saturday...if they stay the same fermentation is complete, then you can rack it to secondary, or leave it for another week or 3 to clear up.
Leave it alone...Don't keep openning the bucket or peeking at it, or think of adding anything...just let it finish out...In other words...
In the mean time sit down and read
