1. ### Is 6800 pF = 6.8 X 10^-3 uF?

yes 6800 pF = 6800 e–12 farads = 6.8 e–9 farads since µF..., and would never be used in practice. It would be 6800 pF or 6.8 nF .

3. ### How do I calculate the high time and low time of a 555 timer circuit? R1= 1K Ohms R2= 68k Ohms C= 2.2 pF ?

2 pF is much too low a value for this application. The timing cap should be at least 1000 pf for any accuracy. It can be as low as 200 pF . in the one-shot mode...
