JDPN, in general it helps to post your recipe when asking specific questions, but I'll assume you followed the Ale to the Chief recipe posted here,
http://www.whitehouse.gov/blog/2012/09/01/ale-chief-white-house-beer-recipe.
Calculating the OG is pretty straightforward with extact recipes, you multiply the amount of gravity points per pound by the number of pounds of extract used. LME contributes about 36 gravity points per pound, DME about 40 points per pound, (source:
http://www.howtobrew.com/section1/chapter3-4.html). Honey is about 40 points per pound.
The math: (36 x 6.6) + (40 x 1) + (40 x 1 ) = about 318 points, divided by 5 gallons = 64 points per gallon, or 1.064.
Now to figure out your estimated FG, the yeast in the recipe is Danstar Windsor dry ale yeast which has an attenuation of about 75% (source:
http://www.williamsbrewing.com/WINDSOR-ALE-DRY-YEAST-P829.aspx).
FG = (1-Yeast attenuation) x OG | .25 x 64 = 16, or about 1.016. So,
if you FG is stable and close to 1.016, you're good to go!
I hope this helps. I'd recommend reading the forum stickies, or the first few chapters of howtobrew.com for more info about the basics of brewing.
