Dont worry about the number of post. Quality, not quantity.

First, I do not recommend going in blind without a soil test.

Two, if you are going to do it anyway, lime it now. I'd guesstimate a minimum of 10 bags for 6000 ft.

Three, that's not a terrible fertilizer recommendation. I might try to find something closer to a 10-20-10. Woods plots in the south and east are terribly low in phosphorus (no idea where you are). Realistically, for only two bags of fertilizer you are going to have to take whatever you can find. I'd up it to 100 lbs the first year, and lighten up on the nitrogen (the first 10 in 10-20-10) if you are planting clover or other legumes. Brassicas, oats, wheat, or chicory need the extra nitrogen.
