you sound on your way to a good grow
it can be a good idea to line the sides of the holes with strong plastic, this will keep neighbouring weeds from sending their horizontal roots into you primo soil
also, the manure could be a little hot, depending on how fresh it is
it's good that it's mixed with straw
i'd probably be digging the holes and adding your 'shit', water it as well as you can, fill the holes, let it drain away, fill again, if possible
then come back, add your couple of inches of topsoil + seed a week, or more, later
you could just plant the seed, plant the popped seed, or plant seedlings...options
they have a better chance of survival if they are a foot high
if you're planting popped seed you want the taproot facing down
sprinkle some snails pellet area the area
that's about all
