First Setup - going through Cycle help!

[clownchick22]

Ok, I've read bits and pieces of other people's posts, however none exacly answer my questions (that I can find anyhow)...

Here is my current Setup:
90 Gallon Hagen Tank
Powerheads Maxi-Jet 1200's (2)
Cannister filter and Hagen Filter (from other tank) for now.
3" DSB (not live)
20 Lbs of LR from LFS
2 Actinic and 2 Marine Glow 40W each in canopy

I am just starting my cycle, and have added 20 Lbs of LR from the LFS last week... some feather dusters (seem to be dying), a few small mushrooms that were hidden in the rock.. a few brittle worms, and snails.. lots of life...
I tested water Sunday and found the following:

PH 7.7
NO2 0.8
NO3 50
PO4 <0.25
amonia 0.3

Any feedback on where the cycle is? In regards to altering peramiters would anyone reccomend additives? Any info would be great!

Thanks.
