Fergie,
Mine was just shy of 800 sqft that includes the mechanical room. Hmmm. You would have double the rated amount of material - almost 40 mils with the kit I used. You could save half , wait till your floor is done, invite your neighbors over, then sell the rest to them! lol...or get 3 one gallon containers and save a gallon of each as a touch up kit. Then put the rest down for a really nice floor!
The actual application took me around 5 hours the first day for base and chips. This included a final sweeping and a little bit of taping. The next morning I put the clear top coat down in about 2 hours.
Prep- took about 8 hours, pressure washed the whole floor, degreased a few spots, scraped glue up, etc. Etching was around 3 hours of the 8 hours.
Got the base boards down tonight, but I did not cope all the joints only miter cuts so I want to fill all the cracks and nail holes with caulk tomorrow evening before taking pics. Did not want to hear all the comments about you should always cope your joints.
