Firstly, water running towards the house always concerns me, because the onus is on you to keep the drainage channel clean. Still, not impossible.
I don't think the sand will matter, if it's the original subsoil, because it will aid drainage. Do make sure it's sharp sand and not the yellow stuff that builders use for cement, because the yellow much has salts in it which will kill plants.
If the garden is prone to waterlogging, then a land drain/french drain might help, but properly cultivated soil under the grass will drain evenly anyway.
Re compost, again, properly cultivated topsoil is fine.You can feed the lawn next spring once it's established. If it's to be done now, it won't need much food and the compost is unnecessary, to my mind.
Gravel boards will be easier to fix before the topsoil is brought in because the soil will bring up the levels and make it more difficult for the fencer to do his job, I'd have thought.
That's what I think.
