I have been using DAP and Fermaid K and was wondering if I just used
Fermaid K without the DAP would that be sufficient?

Generally yes. The excpetion is if your must is severely nitrogen
deficient.

I have been using it without DAP for 3 years with no issues.

Any comparisons; available nitrogen - cost per usage, etc?

DAP is just nitrogen, Fermaid or Superfood contain other things so
they're supposed to better for the yeast overall. There is a table
around the Web that shows what to use for what types of must - some
need both Fermaid and DAP for best fermantation, but in practice, this
is hardly needed - plus you won't get a good wine anw if you have to
deal with grapes like those.

As for cost, this stuff is so cheap overall that it hardly matters -
but DAP is cheaper.

I am curious to know how much Fermaid K and how much DAP one should
use per 100 pounds of grape must? I was thinking 15 grams of Fermaid
per 100lbs of must and 30grams of DAP per 100lbs. I feel with this
combination I should never have any fermentation problems.
